Computer security

The modern world is almost completely based on the world of technology. Almost all fields of the modern life are completely based on the usage of latest technology. However, it is important to understand the amount of risk that is involved with the virtual world. Technology has opened the gateways for cyber crime in a huge way. There are several hackers which have managed to find the key to the extremely vital and confidential information that is passed through the virtual network, from one Internet protocol to another. This factor forced the introduction of e-mail encryption gateways. The basic idea is to provide the required degree of safety to the mails that are being sent and received. There are several extremely confidential data that are being sent. This data needs to be protected correctly from the hackers. It is extremely important to understand that antivirus programs are not enough for the complete protection of the system. It is important to protect the system as well as the entire network from any unwanted activity.

There are several spam websites, phishing sites, virus attacks which the world has started to experience. There are various types of impacts which can take place if the machine faces a virus attack. It is thus, extremely important to secure the machine which is so very crucial in the current world.

There are several ways to secure the computer. You can use firewalls and antivirus programs for computer security. However, the important thing to note in this regard is that, most of these modes have money involved in them. The users would be greatly helped with a free mode of securing the machine. There are several websites which allow the users to check their machines with the latest programs at completely free of cost. It is important for the users to find these websites.

Google™ Remotely Wiping Malicious Apps on Android™

Security is the prime concern for any organization or a person. It is applicable here in case of mobile phones also. We all know that the mobile phone market is being flooded with new and never before models each day. It has gone a long way from the initial stages of the mobile phone industry. The operating systems on mobile devices are prone to several security threats. To combat the situation, the development team of Google Android has come up with some solutions which are safe and easy to apply.

Android team has come up with a solution to malicious threats to your device. It was reported that these malicious applications get your device’s information as IMEI No. and other unique codes that are vital to your device in terms of proper working and safety concerns. But there are other risks involved in it as these exploiters are able to get other data and after that they are able to exploit you and commit some crimes like identity theft.

Taking a serious step towards this, the Android team has taken it seriously and that is why Google has decided to remove infected apps remotely. It is all possible and the user is intimated by the support team of Android. If a device is found infected, a mail is sent to the user.

Things You Can Use to Protect Your Computers From Hackers

Computers can easily be affected by malicious programs and are open to several kinds of security vulnerabilities. In this post I will discuss some very important computer security aspects which should always be kept in mind and adhered to.

Firewall: Firewall is one of the best ways to keep your computer protected from outside world. As the name suggests, it works exactly like a wall of fire and does not let the outside infections, intrusions come inside your computer. However, since new infections and hacking techniques are coming into existence day by day, so it is very important that you keep the firewall updated so that it easily detects and stops such attacks.

Antivirus: An antivirus is an application which has only one purpose, and that is to detect and remove virus infections. It offers several levels of protection for keeping your computer safe and sound. If it is enabled and resident in the memory, it scans the incoming data and checks if it has traces of virus infections or not. If found it straight away intimates you about the same so that the transfer of such data can be stopped. Many antiviruses automatically block such infected data from entering your computer. Another task of an antivirus software is to scan the entire hard drive from time to time and look for any infected file which could have come in to the computer system by external means like CD, Flash drive, e-mail attachment etc. But in order for an antivirus to work properly, it is very important to keep it updated with the virus definitions, otherwise your security software would not be able to detect the infections.

Antispyware: Spyware has the capability of seriously harming data or stealing confidential information. Spyware silently spies the data entered by you and can even steal your bank and other financial information. This kind of program can attach itself with any legitimate system file so that they start when the system starts and always stay resident in the memory spying your activities. One should always install a good quality antispyware on their computers and should also keep the same updated regularly.

Password: Users should always keep strong passwords for their Windows accounts, e-mails, financial sites, and almost everywhere. Your passwords should not contain your name because it is very easy to guess. The password should always contain some numbers and special characters. A password comprising of few numbers and some special characters makes it very difficult to be cracked. As a calculation a 14 character long password which consists of both lower-case and upper-case alphabets, numbers, and some special characters will require several years in getting decoded.

Locking the computer: ‘Windows logo’ key and ‘L’ is the shortcut for locking the computer and one should always remember it, rather make it a habit. Never ever leave your system open, because if you do so it will be very easy for anyone to access your information without leaving any traces. If you tend to forget locking the computer then set it in the screensaver of your computer with a timeout of 1 minute.

Online scams try to capitalize on Japan Earthquake and Tsunami

Online scams and frauds have increased in the past few days, which are aimed at fooling people into making donations for the victims of the Earthquake and Tsunami in Japan. If you get an e-mail asking to donate money for people who have been affected by the Earthquake, it is advised to check the credentials of the sender. The e-mail could be spam or a phishing attack intended to steal confidential personal and financial information such as bank account details, debit/credit card numbers, username, password, etc. Warnings have been issued by the FBI regarding scammers who are posing as officials of charitable organizations, which are actually fake.

The following is a sample phishing e-mail which is an online scam:

While clicking on the website of a charity, ensure that the page is authentic as it could be a copy of a genuine site. Many malicious websites have also reportedly come up with words such as Japan Earthquake in the URL. Social networking websites such as Facebook are also being used by hackers to spread online scams. A link of a video of the Tsunami is being spammed on Facebook. Clicking on the link does not open a video, rather it leads users to like a malicious webpage.

You can take precautionary measures to protect your computer from online scams, frauds, phishing, spam and hacking. Online users should not open unsolicited e-mails or download attachments in such mails. It is suggested that people should not make online transactions for donations through links in e-mails. Use an updated web browser which offers protection against malicious websites and phishing.

Microsoft releases new patches for bug fixes

Microsoft recently issued two bulletins that fixed three holes in the Windows system. One of these holes was rated as ‘critical’ in the Windows XP, Vista as well as the latest Windows 7 operating systems. These fixes were part of the Patch that was issued during the bulletin.

The importance of this patch is quite evident from the vulnerability that Windows was open to due to the critical holes. Along with the operating system, even Microsoft Data Access Components were in a dangerous position without the patch, since the holes could allow attackers to take over a user’s computer if he or she simple viewed a malicious web page.

In addition to resolving this important flaw, Microsoft also took care of another hole that, if left unchecked, could lead to remote code execution if a user were to open a legitimate Windows Backup Manager file that was simply located within the same network directory in which a malicious library file was stored. For the attack to succeed, the user would have to visit a suspicious web-based distributed authoring and versioning or WebDAV, or remote file system.

In addition to this, Microsoft also modified its previous Security Advisory 2488013. This was related to the Cascading Style Sheets, or CSS. They served the purpose of providing an additional workaround for a reported vulnerability in Internet Explorer, and to combat the targeted attacks that were reported.

One of the most important holes of Internet Explorer, the “css.css”, had affected all versions of the Microsoft program, and had been rated as a critical vulnerability. However, in spite of the fix provided for gaping holes in the Windows lineup, security analysts are still looking out for patches that fix the zero-day holes that still persist. The five basic vulnerabilities which have not yet been patched by Microsoft are still in the minds of everyone, and all eyes are on the software conglomerate to provide fixes for these pending issues soon.

Among some of the most jarring holes yet to be patched up by Microsoft, includes a bug in the Internet Explorer program. This bug was actually disclosed by Michal Zalewski, a security researcher for Google, and he had stated that an exploit for this bug is already available on the Internet. In addition to this, he had released a tool for the purpose of finding holes in Internet Explorer and other leading browser software. Microsoft has still not come up with a patch for this bug, and is in the process of assessing it at present.

Microsoft has been on a roll in trying to patch up the several vulnerabilities in its Windows lineup. In the last year, Microsoft had released a patch for 25 vulnerabilities in its Windows operating system as well as Exchange and Office, nine of which has been tagged as critical.
