• Computer Security.
• With hacking and privacy becoming ever growing issues in the cyber space it is becoming very important to make sure your computer is secure. Many corporations have a full time staff that can tend to computer security issues.

• Security through obscurity.
• Security through obscurity or security by obscurity is a controversial principle in security engineering, which attempts to use secrecy to ensure security. A system relying on security through obscurity may have theoretical or actual security vulnerabilities, but its owners or designers believe that the flaws are not known, and that attackers are unlikely to find them. ...
• For example, if somebody stores a spare key under the doormat in case they are locked out of the house, then they are relying on security through obscurity. The theoretical security vulnerability is that anybody could break into the house by unlocking the door using the spare key. ...
• In cryptography, the reverse of security by obscurity is Kerckhoffs' principle from the late 1880s, which states that system designers should assume that the entire design of a security system is known to all attackers, with the exception of cryptographic key secrets. It is, from the original French, "The security of a cypher resides entirely in the key". ... Historically, security through obscurity has been a very feeble reed on which to rely in matters cryptographic. ...
• The full disclosure movement goes further, suggesting that security flaws should be disclosed as soon as possible, delaying the information no longer than is necessary to fix or workaround the immediate threat. ...
• It is sometimes argued that security by obscurity is better than no security. ...
• Many people believe that 'security through obscurity' is flawed because: .
• secrets are hard to keep - in particular, placing information in binary computer code does NOT guarantee its secrecy, and at most requires more effort on the part of the adversary .
• security flaws can be found without access to the secret design .
• It also has a negative impact on research into effective security; it is however very tempting to the ignorant or self-deluded and to politicians who would like their support. ...
• specifically, many forms of cryptography are so widely known that preventing their gain by a national government would likely be impossible; the RSA algorithm has actually been memorized in detail by most graduating computer science students. ...
• security flaws can be publicised, thus removing the obscurity very rapidly .

• Back up your computer data. ...
• Regularly download security protection update "patches". ...
• Check your security on a regular basis. When you change your clocks for daylight-savings time, reevaluate your computer security. ...
• Make sure your family members and/or your employees know what to do if your computer becomes infected. ...
• Make sure you have anti-virus software on your computer! Anti-virus software is designed to protect you and your computer against known viruses so you don't have to worry. ...
• Protect your computer from Internet intruders -- use "firewalls".
• Equip your computer with a firewall! Firewalls create a protective wall between your computer and the outside world. They come in two forms, software firewalls that run on your personal computer and hardware firewalls that protect a number of computers at the same time. They work by filtering out unauthorized or potentially dangerous types of data from the Internet, while still allowing other (good) data to reach your computer. Firewalls also ensure that unauthorized persons can't gain access to your computer while you're connected to the Internet. You can find firewall hardware and software at most computer stores nationwide. ...
• Your computer operating system may allow other computers on a network, including the Internet, to access the hard-drive of your computer in order to "share files". This ability to share files can be used to infect your computer with a virus or look at the files on your computer if you don't pay close attention. ... Don't share access to your computer with strangers! .

• Feeling sick? Blame your computer!.
• It's time once again for Keyboard Korner, the computer-advice column that uses simple, ''jargon-free'' terminology that even an idiot like you can grasp; the column that shows you how to ''take command'' of your personal computer, if necessary by reducing it to tiny smoking shards with a hatchet.
• Today on Keyboard Korner we will address a very important topic: computer security. If you own a computer, or have touched a computer, or have ever shaken hands with somebody who might have touched a computer, you need to take precautionary measures NOW. ... Modern cyberspace is a deadly festering swamp, teeming with dangerous programs such as ''viruses,'' ''worms,'' ''Trojan horses'' and ''licensed Microsoft software'' that can take over your computer and render it useless.
• This is exactly what happened last summer when the ''SoBig'' virus infected computers around the world, causing millions of computer users to be completely cut off from the Internet during what turned out to be a critical phase in the relationship of Jennifer Lopez and Ben Affleck. Fortunately, most of these computer users were able to resume monitoring the situation by turning on their televisions. ...
• If you want to prevent a similar tragedy from happening to you, you should immediately take the following steps to protect your computer from viruses:.
• Determine what version of operating system your computer uses, and write this information on a piece of paper. ...
• Whoa! That was a close one! A computer virus just attempted to take over the Keyboard Korner column WHILE YOU WERE READING IT. ...
• And that's why it is so important that you take certain simple, basic steps to protect your computer. ...
• So we decided to do our own research into computer security, and here's what we learned: There is a Nigerian businessman, Mr. John Ombmwlbmle, who has come into possession of $285 million in cash, and he needs to give 35 percent of it to somebody, and out of all the people on the planet earth, he has chosen Keyboard Korner! All we had to do is send him some banking information and samples of our signature! So pretty soon we will be on ''Easy Street'' and won't have to write this stupid computer advice column for you losers, so ha ha ha!.
• But in the meantime, here are some simple, basic steps that you can take to make your computer secure:.
• GET RID OF TEENAGERS -- Teenagers are a major cause of computer trouble, because they think they're so smart, and they're always messing with things and changing things and installing things and swapping songs and downloading disgusting porno filth that they refuse to share with their parents. To prevent this from happening to you, get a good anti-teenager program such as Teen-B-Gone, which causes the computer, when booted up, to play, at full volume, a video of Mr. ...

• The cardinal rule of security is that No one thing makes a computer secure.
• Making a computer secure requires a list of different actions for different reasons.
• There is a secondary rule that says security is an on going process. No matter how well a system is designed, if it is never changed that gives any potential infiltrator all the time in the world to examine the security for flaws.
• This should, however, serve as a good overview of the types of security measures sometimes taken. ...
• Physical security.
• We have seen a thief use a crow bar to remove a computer along with a portion of the formica table top (they were then foolish enough to take it to a repair shop with the table top still attached). ... A combination of locks and alarms is an excellent theft prevention system for computer labs which must be publicly accessible, particularly at late hours.
• Computer hardware is protected from fire damage by smoke detectors and sprinkler systems just like any other equipment. ...
• These are particularly important if the computer must be used continuously or if your region is prone to severe thunder storms or frequent power outages. ... The modem and mother board can be more readily damaged by lightning hitting a phone line than by lightning hitting the power lines because the computer power supply provides a minimal amount of protection.
• Back ups can be on removable disks, tapes, paper printouts or other computer systems. ...

• Should I be worried about security vulnerabilities?.
• If your business maintains information on computer systems, you should be concerned about computer security vulnerabilities at some level. Your concerns will be much different if you have thousands of computer systems vs even one or two computers.
• Where would I find security vulnerabilities?.
• Many businesses have not discussed security related issues or implemented security related policies. When you consider your security vulnerabilities, you may want to consider the following "layers" of vulnerabilities.
• Internet Security.
• If you have not implemented reasonable security at this or other "network perimeters" (such as connections to vendors or customers), you may be very vulnerable to an attack.
• Security measures can include firewalls, network address translation (NAT), network antivirus, SPAM filtering and more.
• Network Security.
• Security measures can include wireless encryption, maintaining an inventory of physical connections, and more.
• Computer Security.

• Typically this is for computer systems, which is the model we will discuss here. ...
• The 'user' whose access is being controlled (all users in principle, though some users have special privileged access deliberately or accidentally on some systems) may be a real human at a keyboard, or a process / program, on the local or some other computer system. ... If the password given matches that the system has stored for that user, the user is permitted access by the login facility (usually a part of the operating system) to the computer system. The access granted may be limited to certain directories and files, to only certain executables, only for certain times, only for a limited amount of resources (eg, computer CPU time, or disk storage space,. ...
• Examples include logons to computer systems such as e-mail servers, or Illya Kuryakin proving his identity to the U. ... security door with a code word, or a personal_identification_number (PIN) at a bank cash machine. ...
• Passwords are sometimes shared by the members of a group who are thus all intended to have the same access to the computer system, but this is less sensible than individual passwords since the more people (or programs) which know a password the higher the chance that password will become known to others and since membership in such a group may not coincide with the existence of the group. ...
• The security of a password protected system against illegitimate access depends on several factors but all are tied to keeping the password completely secret. ...
• If it is usable only once, many potential security exploits would be rendered ineffective. ...
• At least one University in the US has inadventently made public some of their records which included student name and Social Security number. ...
• If a new password is passed to 'the system' in clear, security can be lost (eg, via wire tapping) before the new password can even be installed in the password database. ...
• Studies of live computer systems have consistently shown (for several decades, for all systems examined, across all examined cultures,. ...
• Conversely if the user selects a less obvious password then, to assist in remembering it, they are likely to write it down somewhere (a Post It note stuck to their monitor being a strangely popular choice), thus compromising the security of the system. ...
• We're doing a security test. ...
• Whether or not the checking process in the computer system (the 'authenticator') actually knows the plaintext of the password. ...
• Even when using encryption procedures to provide increased security, no password system is totally immune to attack. ... By comparing the encrypted outcome of every word (and many word variations) from some word collection (ie, a dictionary), a program can automatically attack many computer systems. ...
