The month of October 2016 is the 13th annual National Cyber Security Awareness Month (NCSAM) here in the United States. Internet (cyber) security continues to be at the forefront of our minds as we push further into the 21st century, and once again President Obama has made a presidential proclamation regarding the need for increased cybersecurity:
Technology plays an increasingly significant role in our daily lives. The rise of the Internet has brought incredible opportunity and new ways of innovating and enhancing our way of life but with great potential also comes heightened risk to our data. Keeping cyberspace secure is a matter of national security, and in order to ensure we can reap the benefits and utility of technology while minimizing the dangers and threats it presents, we must continue to make cybersecurity a top priority. Throughout National Cybersecurity Awareness Month, we recognize the role that individuals can play in enhancing cybersecurity, and we join to raise awareness of the importance of securing our information against cyber threats.

Anti-Virus Web Protection & Spyware Removal | StopSign ...
Kaspersky Internet Security (often abbreviated to KIS) is an internet security suite developed by Kaspersky Lab compatible with Microsoft Windows and Mac OS X. KIS offers protection from malware, as well as email spam, phishing and hacking attempts, and data leaks. Kaspersky Lab Diagnostics results are distributed to relevant developers through MIT[clarify].
Version 6.0 was the first release of KIS. PC World magazine praised version 6.0's detection of malware. KIS detected 100 percent of threats on a subset of the January 2006 wild-list, a list of prevalent threats. The suite detected almost 100 (99.57%) percent of adware samples. KIS has the ability to scan within compressed or packed files, detecting 83.3 percent of the "hidden" malware. However, version 6.0 was criticized for not completely removing malware by leaving Registry entries and files. PC World also highlighted the suite's false positives eight of 20,000 clean files were incorrectly flagged as malicious and its noticeable impact on computer performance. However, data is cached from each scan, making each subsequent scan faster. The firewall blocked all attacks from inside and outside the computer when tested.
The magazine found the graphical user interface to be awkward to navigate. Features such as parental controls and instant messaging protection, found in competing suites from Symantec and McAfee, were not a part of version 6.0. Both CNET and PC World criticized the suite's relatively high retail price, US$79.95.
KIS 6.0 supports Windows 98 SE, ME, NT Workstation 4.0, 2000 Professional, XP Home Edition, XP Professional, XP Professional x64, and Vista. 50 megabytes of free space, Internet Explorer 5.5, and Windows Installer 2.0 are required. RAM and CPU requirements are dependent on the operating system.
Version 7.0 introduced a redesigned GUI. Components were renamed and reorganized; the Anti-hacker module was renamed to the Firewall, and the Anti-Spy module was integrated with the Privacy Control module. PC World described the new interface as "intuitive" and "great-looking".
Parental controls were introduced, with specific settings for different age categories, such as "child" or "parent". Within age categories are content categories, such as drugs or violence. Users can manually configure profiles. Filtering profiles can be associated with users. Since content is filtered at the network level, the feature will work with any Internet browser. The filter relies on a database of known URLs and can analyse websites in real-time. Attempts to access forbidden URLs are logged, and sites visited are tracked as well, raising privacy issues. Limits on Internet access may be set based on time, and chat rooms along with webmail sites can be manually blocked.
Spam filtering integrates with Microsoft Outlook, Outlook Express, Windows Mail, and The Bat!. E-mail content is analysed and scored, and e-mail with scores above two specified thresholds are either marked as "!!spam" or "??probably spam". The Mail Dispatcher feature shows subject and sender information for messages, and allows users to avoid downloading blatant spam by selecting which messages to download. The filter self-trains by analyzing incoming and outgoing e-mail not marked as spam, or by analyzing folders only containing spam or valid e-mail. Senders of verified valid e-mail are whitelisted. E-mail can also be whitelisted or blacklisted based on phrases present in the text. E-mail with non-ASCII characters or invisible text can also be blocked. However, version 7.0 had a relatively poor showing, misidentifying 30 percent of valid messages in PC Magazine testing. 30 percent of spam also made to the inbox.
Protection against data leaks was incorporated in this release. The suite warns users when programs attempt to access or send data from certain areas, such as where Internet Explorer stores webform information.
Malware protection was mostly positive in detection and disinfection tests by AV-Test.org. Version 7.0 detected 100 percent of wildlist threats. Using one-month-old signatures and a set of new malware, however, detection fell to 14 percent. Files were scanned at 5.24 megabytes per second. Version 7.0 successfully identified all six actively running rootkits, four of six inactive rootkits, and was only able to remove two of six rootkits. The firewall correctly blocked all attempted outside connections, with a reasonable level of security when left on default settings.
This version drops support for the Windows 98, 2000, and NT. Windows XP Service Pack 2 is required, except in the case of XP Professional x64 edition. Vista is supported as well. RAM and CPU requirements are dependent on the operating system. 75 megabytes of free space, Internet Explorer 5.5, and Windows Installer 2.0.
This version introduces a revised user interface, an application filtering module, an updated anti-virus engine, and a vulnerability scanner. The main window separates settings in four categories, compared to eight in its predecessor. A status bar changes colour (green, yellow, and red) to reflect overall program status and flashes to divert attention when needed. PC Magazine also noted pop-up notifications were kept to a minimum.
Kaspersky claims the core anti-virus engine was revised to increase scan speed. PC Magazine found an initial scan took over two hours, however subsequent scans took two minutes to complete. However, malware detection was relatively low in comparison to other anti-virus applications tested. Out of 650 thousand samples, version 8.0 detected 95.6 percent. The top score was around 99 percent. Using two-week-old signatures, version 8.0 detected 52 percent of viruses in a different set of samples. Kaspersky also blocked about 60 percent of malware based solely on behaviour. The top performers scored 55.3 percent and 80 percent respectively. Version 2009 detected 98.1 percent of adware. However, PC World noted to achieve that kind of performance, users will have to modify program settings. On default settings, KIS allowed Zango to install. To block the installation, users must enable KIS to scan for "other malware".
The Security Analyzer looks for operating system and program patches. It also looks for vulnerable system settings, presenting users with a list of recommended actions to prevent malware from gaining access to a system. However, PC World criticized the amount of computer jargon used and lack of information about how adjust settings appropriately. On the other hand, PC Magazine found the feature straightforward, and often the solution involved downloading and installing an update.
KIS uses a whitelist by Carbon Black to classify trusted and malicious programs. Malicious programs are not allowed to run at all. Unknown programs falling in between the two categories are restricted in the actions they can perform. Its firewall blocked all attacks in PC Magazine testing. Phishing protection was introduced in this release. Testing by PC Magazine found the feature blocked 44 percent of phishing URLs. Internet Explorer 7 blocked 67 percent of the URLs, and Mozilla Firefox blocked 81 percent.
Spam filtering now integrates with Mozilla Thunderbird and scans NNTP traffic. Spam can be automatically diverted to its own folder. When using an unsupported e-mail client to download POP3, IMAP or NNTP mail, Kaspersky will still generate a report of all messages. However, in an unsupported client, there will be no toolbar nor will the program classify any messages as spam in the client itself.
Version 2010 of Kaspersky Internet Security introduced an overhauled user interface and a sandbox for running applications in a virtualized environment. The 220.127.116.116 build of KIS 2010 fully supported the Windows 7 operating system.
The beta version was released for all windows users on 8 June 2010. This version included a new interface, as well as a gadget only available for Windows Vista and Windows 7 users. PC Mag rated this version "very good" (4/5 stars). Its firewall was noted to be very good, but that made up for its only adequate malware detection rates. Two critical fixes have been released by Kaspersky Lab, making the current version 18.104.22.1686.
On 1 March 2011, Kaspersky released the first build of version 2012, it came out as beta version and in English, French and Russian version, with more versions due out later. On 7 June 2011 Kaspersky Lab announced the commercial release of Kaspersky Internet Security 2012 in France, Germany, Switzerland. The current version is 22.214.171.1244.
The beta version was released for all windows users on 3 March 2012. This version includes an interface which looks (currently, at least) much like Internet Security 2012. There is no Safe Run option, no Proactive Defense, while instead the behavioural monitoring System Watcher seems to be taking greater responsibility for detecting malware and a Safe Banking feature has been added.
The release candidate (build 126.96.36.19988 RC) was released for all windows users on 20 July 2012.
The Final Version was released on 28 August 2012 build 188.8.131.5290
Beta testing started on 12 March 2013. This version introduced a Windows 8 like GUI design. The final version was released on 3 August 2013 build 184.108.40.20651 in India and Russia, then on August 13 in the USA and August 27 in the UK. The 2014 release was frequently characterized as inferior to user expectations, largely due to its removal of a range of granular fine-tuning options in 2013 and earlier, which were used by experienced users; a number of these were added back in the 2015 beta by the time of its technical release (build 463).
As of February 13, 2014 build 220.127.116.1151(E) was released. Build 18.104.22.16851(I) is the latest (current) version.
In April 2014, a beta version of the 2015 product, build 463, was released, followed by a technical release preview, of the near-complete 2015 product. The first official release of the product was in Bangladesh in June 2014.
In March 2015, Bloomberg accused Kaspersky of having close ties to Russian military and intelligence officials. Kaspersky slammed the claims in his blog, calling the coverage "sensationalist" and guilty of "exploiting paranoia" to "increase readership".
As a result of alleged Russian involvement in the 2016 Presidential Election and ongoing investigations, the Department of Homeland Security officially banned the use of the Kaspersky Internet Security by the United States federal government in September, 2017.
As of December 12, 2017, the use of Kaspersky software is banned from use by the American federal government by law.

COMODO Internet Security Premium is an antivirus system that aims to protect your system, files and folders against online threats. It includes an antivirus module, combined with firewall features build an unbreakable shield.
COMODO Internet Security Premium offers to change your DNS servers to COMODO SecureDNS servers (it has a description), and to enable "Cloud Based Behavior Analysis" of unrecognized programs by submitting them to COMODO.
When the program is launched, you are welcomed by three windows. In one of them, COMODO searched for updates, another one informed us of how the firewall had detected a new private network that our PC was about to join, and another one which is the software's interface.
Updating takes several minutes, after which COMODO runs an automatic scan on your computer (which takes a really long time, but it's thorough). The GUI is very eye-catching and simple to follow.
COMODO seems to have a lot of features for each main function, but they are well organized. The antivirus section lets you run or schedule a scan (a full scan, on critical areas, or a spyware scan), configure the scanner settings, view antivirus events and quarantined items, but also submit suspicious files to COMODO to be further analyzed.
The firewall lets you view events and alerts that were possibly triggered by attacks on the computer, define a new trusted or blocked application, create a set of global rules, and configure various options.
Defense+ has some interesting features, such as running a program in the Sandbox (a "safe haven" for untrusted, restricted, limited or partially limited applications), adding or removing files to and from your local safe executable database, and viewing unrecognized files (which are automatically placed in the Sandbox until further notice).
Surprisingly enough, COMODO uses very little CPU and memory resources while scanning is active. But other system applications run slower.
To sum things up, COMODO Internet Security Premium is a brilliant security application, but that's only our opinion. You have to test it for yourself.

These days you cant be too careful with your computer security setup. With more and more of our daily transactions happening online, its very important to ensure that your computer is protected from the wide array of threats that are circulating on the internet.
In thisAvast Internet Securityreview we cover one of the more popular software programs designed to protect your computer. We get a lot of emails from people asking whether or not this software is worth the cost, so we figured an in-depth review was in order.
A quick note about versions: this review covers Avast Internet Security, which is a step above Avast Free Antivirus. There are also upgraded versions called Avast Premier and Avast Ultimate, which have more features included.
Editors note: We bought this software with our own money and have not been asked by Avast to write this review.
I want to lead with my overall impressions of Avast Internet Security for those who dont want to read a long article then you can drill down and read about all the features in the rest of the review below if you so desire.
Overall I wasnt expecting to be thrilled with Avast Internet Security due to a botched installation when I first installed the software, but my opinion drastically changed once I reinstalled it and found it was working swimmingly.
I actually had more fun than I usually do when reviewing these security software suites because Avast is easy to use, intuitive, and has quite a few bells and whistles that you wont find in other security solutions. I also found their whimsical online and in-program help documentation to be refreshing.
Avast Internet Security is the basic version, a step up from the Avast Free Antivirus. However even this basic level software packs a lot of utilities.
Avasts support was responsive and helpful when I had an issue connecting my online account with my software, and the help and documentation on the website is very well laid out and clear.
I highly recommend this software as a virus and malware solution. Theres a lot of debate on the internet over which security suite is better, however Avast continues to be highly recommended by many computer professionals. No software will be 100% perfect, so if Avast has the features that you want its a great lightweight solution for protecting your data.
Get Avast Internet Security
Avast was a quick download and install on my Microsoft Surface Pro 4 running Windows 10. The installation was a touch slower than other security apps Ive used, but that could be due to a slightly slower speed of internet as I was working remotely at the time.
After installation I ran the Smart Scan, and the program finished in about 6-7 minutes. The results were interesting as the software scans more than just for malware and viruses. It also found three software programs that needed updates (and allowed me to update them right from the dashboard), and pointed out that the coffee shops WiFi password was weak.
The scan is pretty typical of most security software suites. You can customize the scan in the settings to scan for only the things you want it to for example, you can disable scanning for software updates if you so desire.
Its important to know if your antimalware and antivirus software tools are up to snuff. The good news is that Avast consistently gets top scores in the AV Comparatives monthly score tallies. AV Comparatives is an independent group that tests the top computer security software tools.
You can check out their results here.
Avast Internet Security and all of the other software tools in their library of programs are very intuitive and easy to use. Each setting has a large icon-centric button, and each feature has a small i that you can click that explains the features functionality and uses. This is helpful because even the basic Internet Security program comes with a lot of bells and whistles to play with.
Most computer users will find using Avast to be easy to use and almost fun in fact its the most fun security suite Ive tested. I cant quite put my finger on why, I think its the simplicity and intuitive way everything is laid out.
The black on black color scheme is also a nice touch, making the software feel very updated and modern.
Avast notified me that I had 13 passwords stored in my internet browser, and it asked me to start using Avast Passwords, a password keeping system. I actually use LastPass for that right now, but it seems like a good option for someone who doesnt have a password solution yet. For those who dont know, these password solutions are a great way to enable yourself to use unique and difficult passwords for all of your sites so you dont get caught with your pants down by using the same password for all your sites (something I used to do and I had a minor panic attack when someone hacked my Facebook account and got that password and my email).
You also have the option of storing credit card numbers as well with the ability to auto-fill them when online shopping.
Avast Passwords also has a cool feature called Secure Notes where you can safely store small secure things. Need a place to store your security key for your 2 Factor Authentication app? This could be a good place, instead of a notepad file somewhere on your computer or even writing it down on a paper that could get lost. Lets face it, every once in a while we need to keep a secure number on hand.
After taking my Surface Pro to the coffee shop to do some additional work and continue testing Avast, the software popped up notifying me that I had connected to a new WiFi network. It then gave me the option to scan the network, which scanned the router, and all the devices connected to it meaning ALL the various laptops and phones that were on the network. I dont suspect this coffee shop to be a hotbed of hacker activity, so it was not surprising to find that all the devices came up clean.
This feature is useful for detecting problematic devices that might be on a public network scanning it for activity. Im not usually that paranoid but you can never be too careful. This is useful, however, if you want to do some banking or personal transactions on a public network and want to scan it before using it.
Avast Internet Security has quite a thorough settings menu, where you can tinker with excluded software, customize the Smart Scan, and do so much more. There is really too much to list for this basic review of the software but suffice it to say that if theres something you want to turn on or off or customize, theres a 90% chance youll be able to do it within the settings.
You can even customize the scan parameters in the virus scan portion of the Smart Scan. Most computer users probably wont touch this or need to stray from the default settings, but advanced users will be thrilled with this.
Avast is available for PC, Mac, Android, iPhones and iPads, and even networked smart devices in your home. That makes Avast one of the most compatible software programs out there it covers most devices while many companies stop at just PC and Mac.
Each of these devices needs its own separate version of Avast, however, so unfortunately you cant just buy it once to cover all of your devices. However, youll only need to deal with and learn how to use one program if you want to get Avast security on all devices which is a time saver. Not many people want to learn how to use a bunch of different security software solutions.
Get Avast Internet Security
Avast Internet Security has two higher levels to choose from that will get you a few more bells and whistles. I recommend all the levels, as I think all their tools are useful. However, just ensure that you need the additional tools they offer and you dont already have something similar.
Check this link for Avasts comparison web page.
For Avast Premier, you get webcam spying protection, a file shredder (completely delete a file), and the ability to automatically update apps and software.
With Avast Ultimate you get everything from Premier plus a few other Avast software tools: Avast Cleanup Premium which helps clean up file clutter on your computer, Avast Secureline VPN which shields your location and provides an extra layer of security to your internet browsing, and Avast Passwords Premium which allows you to store your passwords and also warns you of password leaks.
In my opinion, Avast Ultimate is worth it just for the easy to use Secureline VPN, which is very useful. Personally, if you were thinking of upgrading from the basic level I would probably skip Premier and just get Ultimate and get everything.
We used Ultimate for this review so we could be sure to test all the features and be able to write them up. I will say that the SecureLine VPN service works very well and its worth the price. SecureLine VPN is available as a standalone product as well.
No matter what level you are interested in, Avasts line of security software comes highly recommended from me. I had a lot of fun reviewing this software and found it to be refreshing from the rest of the security software thats out there. No program will always protect you 100%, but picking one of the top line programs will give you the best shot at staying safe on the net, and Avast is up to that challenge.
We recommend going with Avast Internet Security or going all the way up to Avast Ultimate.

Internet Security Lectures by Prabhaker MatetiPrabhaker Mateti
Abstract:Data integrity and privacy on the Internet primarily rests on usingcryptography well. Unfortunately, it is easily compromised by errorsin (operating) system configuration. This lecture is a quick overviewof cryptography as relevant in Internet security and passwords.
Data integrity and privacy on the Internet primarily rests on usingcryptography well. The design and implementation of cryptographyrequires deep understanding of discrete mathematics and number theory.Unfortunately, when cryptography is deployed carelessly, it is easilycompromised by errors in (operating) system configuration. Thislecture is a quick overview of cryptography as relevant in Internetsecurity and passwords.
A cryptographic encryption algorithm, also known as cipher,transforms a "plain text" (e.g., humanreadable) pt and outputs cipher textct as the output,
so that it is possible to re-generate the pt fromthe ct through a companion decryption algorithm. Notethat we said "for example, human readable" and not"that is, human readable" as an explanation for the phrase"plain text". Often, the so-called "plain text"is human un-readable binary data that is ready-to-be-used by acomputer.
Ciphers use keys together with plain text as the input to produce cipher text. It is in the key that the security of a modern cipher lies, not in the details of the algorithm.
Roughly speaking, computationally infeasible means that a certaincomputation that we are talking about takes way too long (hundreds ofyears) to compute using the fastest of (super)computers.
Suppose our key is a 128-bit number. There are
128-bit numbers starting from zero (i.e., 128 bits of 0). Torecover a particular key by brute force, one must, on average, searchhalf the key space:
If we use 1,000,000,000 machines that could try 1,000,000,000keys/sec, it would take all these machines longer than the universe aswe know it has existed to find the key.
This is not the same thing as saying that computationalinfeasibility is the same idea as Turing-incomputable. Nor is it thesame thing as saying that you cannot make a lucky guess, orheuristically arrive at a possible answer, and then systematicallyverify that the guessed answer is indeed the correct answer, all donewithin a matter of seconds on a lowly PC. Here is an example:Microsoft Windows NT uses the DES encryption algorithm in storing thepasswords. Brute-forcing such a scrambled password to compute theplain text password can take, according to Microsoft, "about abillion years." But the L0pht team( http://www.l0pht.com) claims thatL0phtCrack breaks Windows passwords in about one week, running in thebackground on an old Pentium PC.
In the context of cryptography, the factorization of an arbitrarilylarge number N, into its constituent primes, determining the powersn2, n3, n5, n7, etc. of the primes, is computationally infeasible --as far as we know.
N = 2n2 * 3 n3* 5 n5 * 7 n7* ...
Based on this, the decryption is computationally infeasible. Note thatthis is assuming that we are using known methods, including brute force.
Is it possible that some one or some country has actuallydiscovered fast algorithms, but chose to keep them secret, for these tasksthat we believe to be computationally infeasible?
A hash function maps input sequences of bytes into a fixed-lengthsequence. The fixed length is considerably shorter than thetypical length (thousands of bytes) of the input, and hence thefunction is a hash function.
The nature of all hash functions is that there must exist multipleinput sequences that map to the same hash. The inverse is amathematical relation, not a mathematical function. But, good hashfunctions have the following properties: It is hard to find twostrings, from the expected set of typically used strings, that wouldproduce the same hash value. A slight change in an input stringcauses the hash value to change drastically.
A "one way" hash function is designed to be computationallyinfeasible to reverse the process, that is, to algorithmicallydiscover a string that hashes to a given value.
One-way hashfunctions are also known as message digests (MD), fingerprints, orcompression functions. The most popular one-way hash algorithms areMD4 and MD5 (both producing a 128-bit hash value), and SHA, also knownas SHA1 (producing a 160-bit hash value).
As of 2006, both MD5 and SHA1 are considered separately broken. Thatis, given plain text p, it is possible to modify p to a desired p' sothat md5(p) == md5(p'); similarly, for SHA1. What is not known is ifwe can modify p to a p' so that md5(p) == md5(p') and sha1(p)== sha1(p').
Symmetric-key cryptography is an encryption system in which thesender and receiver of a message share a single, common key to encryptand decrypt the message. Symmetric-key systems are simpler andfaster, but their main drawback is that the two parties must somehowexchange the key in a secure way. Symmetric-key cryptography issometimes also called secret-key cryptography.
If ct = encryption (pt, key), then pt = decryption (ct, key).
The most popular symmetric-key system is the DES, short for DataEncryption Standard. DES was developed in 1975 andstandardized by ANSI in 1981 as ANSI X.3.92. DES encrypts data in64-bit blocks using a 56-bit key. The algorithm transforms theinput in a series of steps into a 64-bit output.
IDEA (International Data Encryption Algorithm) is a block cipherwhich uses a 128-bit length key to encrypt successive 64-bit blocks ofplain text. The procedure is quite complicated using subkeys generatedfrom the key to carry out a series of modular arithmetic and XORoperations on segments of the 64-bit plaintext block. The encryptionscheme uses a total of fifty-two 16-bit subkeys.
Blowfish is a symmetric block cipher that can be used as a drop-inreplacement for DES or IDEA. It takes a variable-length key, from 32bits to 448 bits, making it ideal for both domestic and exportableuse. Blowfish is unpatented and license-free, and is availablefree for all uses.
Public key cryptography uses two keys -- a public key knownto everyone, and a private or secret key that is safeguarded. Public key cryptography was invented in 1976 by WhitfieldDiffie and Martin Hellman. For this reason, it is sometimes alsocalled Diffie-Hellman encryption. It is also calledasymmetric encryption because it uses two keys instead of one key. The two keys are mathematically related, yet it is computationally infeasible to deduce one from the other.
Unfortunately, public-key cryptography is about 1000 times slowerthan symmetric key cryptography.
The most well-known of the public-key encryption algorithms is RSA, named after its designers Rivest, Shamir, and Adelman. The un-breakability of the algorithm is based on the fact that there is no efficient way to factor very large numbers into their primes.
An example of the above numbers: rsa.txt. Look up the man page: openssl(1).
The e and d are symmetric in that using either ((n,e) or (n,d)) as the encryption key, the other can be used as the decryption key.
The only way known to find d is to know p and q. If the number n is small, p and q are easy todiscover by prime factorization. Thus, p and q are chosen to be as large as possible,say, a few hundred digits long. Obviously, p and qshould never be revealed, preferably destroyed.
Encryption isdone as follows. Consider the entire message to be encrypted asa sequence of bits. Suppose the length of n in bits is b. Split the message into blocks of length b or b-1. A block viewedas a b-bit number should be less than n; if it is not, choose it to beb-1 bits long. Each block is separately encrypted, and theencryption of the entire message is the catenation of the encryptionof the blocks. Let m stand for a block viewed as a number. Multiply m with itself e times, and take the modulo n result as c,which is the encryption of m. That is, c = m^emod n.
Decryption is the "inverse" operation: m = c^dmod n.
The Digital Signature Algorithm (DSA) is a United States Federal Government standard for digital signatures.
An example of the above numbers: dsa.txt.Look up the man page: openssl(1).
Public-key systems, such as Pretty Good Privacy (PGP), are popular for transmitting information via the Internet. They are extremely secure and relatively simple to use. You need to retrieve the recipient's public key from one of several world-wide registries of public keys that now exist to encrypt a message.
When John wants to send a secure message to Jane, he uses Jane's public key to encrypt the message. Jane then uses her private key to decrypt it.
In real-world implementations, public keys are rarely used to encrypt actual messages because public-key cryptography is slow. Instead, public-key cryptography is used to distribute symmetric keys, which are then used to encrypt and decrypt actual messages, as follows:
A digital signature is a way to authenticate to a recipient that a received object is indeed that of the sender.
The public key-based communication between Alice and Bob described above is vulnerable to a man-in-the-middle attack.
Let us assume that Mallory, a cracker, not only can listen to thetraffic between Alice and Bob, but also can modify, delete, andsubstitute Alice's and Bob's messages, as well as introduce newones. Mallory can impersonate Alice when talking to Bob andimpersonate Bob when talking to Alice. Here is how the attackworks.
A man-in-the-middle attack works because Alice and Bob have no wayto verify they are talking to each other. An independent third partythat everyone trusts is needed to foil the attack. This third partycould bundle the name "Bob" with Bob's public key and signthe package with its own private key. When Alice receives the signedpublic key from Bob, she can verify the third party's signature. Thisway she knows that the public key really belongs to Bob, and notMallory.
A package containing a person's name (and possibly some otherinformation such as an E-mail address and company name) and his publickey and signed by a trusted third party is called a digital certificate (ordigital ID). An independent third party that everyone trusts, whoseresponsibility is to issue certificates, is called a CertificationAuthority (CA). A digital certificate serves two purposes. First, itprovides a cryptographic key that allows another party to encryptinformation for the certificate's owner. Second, it provides a measureof proof that the holder of the certificate is who they claim to be -because otherwise, they will not be able to decrypt any informationthat was encrypted using the key in the certificate.
The recipient of an encrypted message uses the CA's public key todecode the digital certificate attached to the message, verifies it asissued by the CA and then obtains the sender's public key andidentification information held within the certificate. With thisinformation, the recipient can send an encrypted reply.
The most widely used standard for digital certificates is X.509,which defines the following structure for public-key certificates:
You can obtain a personal certificate from companies likeverisign.com or comodo.com.
Threats on the Internet are getting better at penetrating computer systems. Hackers and cybercriminals are developing malicious software that can damage anything from personal computers to mainframes running an entire company. That is why it is necessary to put security layers in place. However, there are several types of security applications. It can be quite confusing for anyone unfamiliar with such programs. Specifically, many experts recommended installing an antivirus program and Internet security.
But, what's the difference between the two? Aren't they the same?
A heuristic is a method of monitoring and evaluation the activities of an application. The antivirus will then decide if it behaves like a virus or not. It will notify the user of any suspicious activities on the computer along with suggested actions. While it is not 100% accurate, this method allows security experts and developers to keep up with the rapidly increasing number of virus online.
Antivirus applications provide a specific security function: protect your computer from virus. Because of this, it can run in the background without any significant effect on the computer's performance. It uses a small amount of memory and CPU. Most of the time, users set their antivirus programs to run immediately during boot. Scheduled scans and updates are also recommended to make sure that your antivirus has the latest virus signatures.
What is an Internet Security?
The firewall protects real-time attacks by filtering any suspicious threats from the Internet and network. The anti-malware and anti-spyware aim to protect the computer against threats which are entirely different from a virus. Malware and spyware are programs which can damage the computer, steal sensitive information, and even hold your system hostage for a ransom.
Internet security suites make it easy to track and monitor your computer's security health. Some even aim to become total computer solutions by including tools such as defragmenting tools, memory cleanup apps, uninstaller, and network monitoring tools, which makes it easy to maintain your computer's health in one place.
However, running an internet security suite takes more computing power than antivirus programs. It still depends on your system. But, older computers may find it challenging to keep Internet security suites running in the background. It demands more memory which slows down some applications and computer functions significantly.
Antivirus Vs Internet Security
Where does anti-malware fit in all of these? As mentioned above, most Internet security come with anti-malware programs as its core function. However, anti-malware programs can also offer multiple services. An excellent example is MalwareFox. It includes features which strengthen your computer security, Aside from scanning for malware, it also has ransomware protection. It protects your system from dangerous ransomware that aims to extort money from you.
MalwareFox also cleans your browser which provides better and faster browsing performance. It also protects your system by analyzing suspicious files and promptly blocks them. The Zero-Day Attack Protection ensures that your system is protected even from the unknown threats. More importantly, unlike Internet security suites, it is light enough to run in the background without affecting your system. MalwareFox can also scan your system in less than five minutes using its Smart Scan Mode.
Anti-malware is a perfect tool for those wanting to have additional protection to run alongside antivirus programs. It is also lighter than total security suites so that you can run it in the background. Most come with features that you will regularly use as your main security functions.
Experts suggest downloading a primary antivirus program. Then, download a secondary solution which can handle most of your security needs. It depends on your needs and what you do online. Anti-malware is appropriate for basic users. Advanced users who download files often, visit various websites and receive a lot of emails may consider Internet security suites at those offer more layers of protection.
