Remember, Hackers are not only threat to your computer, but also they can harm other computers by using your computer

• Hackers use creative measures to gain unauthorized access to your computer and then use that access to steal your identity and commit fraud.
• Use strong passwords or strong authentication technology to help protect your personal information for Avoiding such type of attacks
• Know who you're dealing with online.

August 29^th  :

Though the software is downloaded from trusted site, scan the downloaded part, before using them

• It is always recommend to get the file from the download section of the publisher's home page
• There are some softwares that will comprehensively scan your system's memory, registry, hard, removable and optical drives for known malware during the processing time. Use them regularly to scan downloaded files also.

August 28^th  :

Turn off the computer or disconnect it from the network when not in use
 

• Using the Turn Off Monitor we can Conserve or Save Energy
• The external hard drive is less likely to die if you don't always keep it on for always
• Turning off the computer provides the safety from the security attacks.

August 27^th  :

Always keep the desktop firewall on
 

• A desktop firewall or a personal firewall is an application which controls network traffic to and from a computer, permitting or denying communications based on a security policy.
• Personal firewalls are typically designed to use by the end users. They are intended to protect the systems on which they are installed.
• Some features of personal firewall:
• Provide the user with information about an application that makes a connection attempt
• Monitor applications that are listening for incoming connections
• Sometimes gathers malware and other unwanted programs if you don’t scan you computer everyday
• Personal firewall (Desktop firewall) comes integrated with almost every operating system.

• It is the name of a computer file applied to indicate the file format of its contents.
• By default some of the operating system file extensions are not shown.
• Malicious users have tried to spread computer viruses and computer worms by using filenames like love-letter-for-you.txt.vbs.
• So it is better to display the file name extensions.

• A patch is a small piece of software designed to fix problems
• Security patches are additional pieces of software developed to address security vulnerabilities
• The security vulnerabilities include viruses, Trojans and back doors which opens the door for the hackers remotely
• It is an important part of every IT administrator’s responsibility to maintain a secure network by ensuring that the latest security patches and OS service packs 

• When you visit the certain web sites read the web site policy agreement completely if you agree then click ok otherwise don't
• It will come in the form of a pop up that informs you that you are infected with a virus.
• The pop up then offers a link to click on or visit to get a free scan of your computer.
• Downloading this free software actually infects you with a virus that you then will need to pay to get rid of

• Keyboard loggers is a utility which automatically monitors and records all the activities performed by the user on the system like visited websites screen shots, email passwords and keystrokes from the keyboards in invisible mode.
• So always use the virtual keyboards especially when you are on the public Internet
• Trojans are the computer programs when installed in the computer gives the access to the unauthorized users from the remote computers
• For removing the Trojan horse from the computer use the updated anti-virus with the regular patches

• The Internet is a global system of interconnected computer networks.
• Ad ware and spy ware are the computer programs which harms the web browser securit.
• These computer programs automatically plays, displays, or downloads advertisements to a computer when it is connected to Internet.

• It is the defense against hardware failure, floods and the damage caused by a security breach
• You should keep regular backups of your system and files
• Use rewritable media such as tapes or disks
• The first requirement is to calculate how much data you need to backup and then select the type of backups
• Monitor the backup process. Always keep an eye on the backup process

• Always make sure to backup all important information and store them in a safe place separate from your computer.
• Make regular backups of critical data
• Consider make a boot disk on a CD in case your computer is damaged or compromised by a malicious program. Obviously, you need to take this step before you experience an aggressive violation of your system.
• To serve in recovering from a security breach or hard disk failure, create a boot disk on a floppy disk or CD which will help when recovering a computer after such an event has occurred. Remember, however, you must create this disk before you have a security event.
• Use software backup tools if available, and store the backup disks somewhere away from the computer.

• We need to delete the sensitive data if it is not in use because there is a risk for hacker to hack sensitive information
• One should clean all the data or personal information before they logout the computer
• If the data is stored in hard disk, one should protect the data by backup or duplicate the data
• We can delete data by "rm" or "del" command
• Generally the sensitive data is stored in t he excel or word document ,so one way to limit the  privacy data is to change the program settings
• From Tools menu options security under privacy option  Remove personal information from file properties on save and warn before save, printing, changing, or sending a file and click OK
• The data must be securely removed from the media once the data and/or device are no longer required in order to prevent unauthorized disclosure of the data. This is particularly true if the device contains sensitive data.
• If a device contains highly sensitive data, wiping, degaussing, and destruction could all be used.
• Use wiping utilities to erase the complete data if it not in use

• To avoid risk, decide about what information is to be put on portable devices assuming that they will be lost or stolen at some point.
• Do not store sensitive information on portable devices; instead keep the copy of the information on these devices.
• The less sensitive data you keep on a portable, the less you need to worry about sensitive data exposure if the device is lost or stolen.
• If storing sensitive information on a portable device is unavoidable:
• Store the least amount of data possible.
• Delete, mask or truncate sensitive data elements whenever possible.

• Erase or Destroy the sensitive information before recycling or throwing it away because the hackers / thieves do Dumpster diving for getting that sensitive information
• Dumpster diving: It  is the practice of going through trash to obtain valuable information
• Any sensitive information which is written on paper or electronic that is thrown away intact is vulnerable to dumpster diving
• So, in order to protect the sensitive information from stealing we should not write the sensitive information like usernames, passwords, credit card details...Etc on papers or any where.
• Try to remember them or store it in computer by keeping strong passwords or by encrypting the data. So that the unknown persons cannot access the data which is stored in the computer

• It is a good practice to backup important files or data once in a while using a CD-RW or DVDRW
• You will need to have software like Roxio Easy CD Creator and Nero that enables you to burn your backup files or folders
• To backup Files or Folder on your computer, first you will need to know the directory of your documents.
• Common directory to store files and folders is My Documents folder on your desktop
• Backing up means making a copy of a file or files, to be kept somewhere safe, away from the copy you are working on
• Most of the time, your PC will behave perfectly. However, software and hardware failure, virus attacks and, of course, human error accidentally etc.

• There are many reasons why your company should have admission to several full system backups.
• A single backup could fail. Tapes, CDs and hard drives all wear out in time, so you shouldn't rely 100% on a single backup to store your data.
• The more copies you have, the less likely you are to lose all of your data to wear, fire damage, water damage, etc.
• In the case of accidental deletion, data loss is often noticed days after it occurred, which means that if your only backup is from last night, you have no way of retrieving the data.
• Restoring files that were deliberately deleted months or even years ago, when you thought you would never need them again, can often be of great benefit.

• Don’t keep sensitive data in portable devices such as laptop computers, CDs/floppy disks, memory sticks, PDAs, data phones, etc
• These items are extra vulnerable to theft or loss.
• Always store sensitive data in encrypted format
• Make sure that data is password protected
• Lock up portable equipment and sensitive materials
• Don’t leave sensitive information lying around, including on printers, fax machines, or copiers
• Take special care with a laptop that includes sensitive data; in the event of theft, not only will the laptop be lost, any sensitive data on it will be compromised.

• Don’t put the sensitive data on USB keys, CDs, local hard drive or flash drives it may be threat if you lost the devices or stolen or misplaced
• Generally USB keys are very convenient and highly portable, which means they can be easily lost and potentially fall into the wrong hands.
• To transport files from computer to computer, consult the IT Knowledge Base to learn how to encrypt data when using a USB key, burning CDs or copying data onto laptop drives.
• Be sure that sensitive data is encrypted and then stored in USB’s, CDs or laptop drives
• Sensitive data should be encrypted when it is transmitted

• Any printouts that might contain sensitive information should also be locked away.
• Choose secure printing practices and avoid printing personal records.
• For networked printers, set up printers so that retrieving printouts requires a password.
• Destroy all documents that contain personal information by shredding them.

• Always check the personal address book and remove incorrect entries to avoid failure delivery of emails
• Always check that the addressee names are correct and be particularly aware of personal or global address groups
• Keep the number of e-mails in your mailbox to a minimum
• Use a Personal Address Book

• Frequently test your data and update the data
• Use option like Automatically backup your critical data to a local disk
• Verify that the data are entered into the correct fields in the database table. This verification requires opening and inspecting data sets at the table level.
• Validate your most critical security weakness
• Test network and endpoint security
   

• Safeguarding data involves adding the necessary layers of security and controls to adequately ensure that sensitive data is not at risk of being compromised.
• Regularly back up the data on your laptop or desktop or smart phone
• One of the keys to document or data protection abilities is password protection
• The simplest way to protect your data is to make a copy onto a second physical drive.
• Protect yourself against viruses and Trojan horses that may steal or modify the data on your own computer and leave you vulnerable by using anti-virus software and a firewall
• Regularly scan your computer for spyware
• Simply deleting a file does not completely erase it. To ensure that an attacker cannot access these files, make sure that you adequately erase sensitive files
• Turn off your wireless and Bluetooth connections if you're not using them

• UPS (uninterruptible power supply) is used to protect against sudden loss of power
• Sometimes sudden surges or drops in supply can also cause physical damage to computer components
• The computers are plugged into the UPS, and if the mains power cuts out, the UPS provides enough power for the computers to shut themselves down and save all their information.
• Complete loss of power can cause the obvious problems of lost data and hardware damage
• It is necessary to consider the size of the load that is to be connected to the UPS. The load may consist of a specific type of computer, workstation, mini-mainframe, hard disk drive, or test equipment.
• Once the equipment requiring a continuous power source is identified, the necessary rating of the UPS system can be determined by adding the volt-ampere (VA) rating on the nameplate of the equipment to be served by the UPS.

• Do not download the software for which you have no license or not registered which violates  the license agreement and the users who download from these sites may get in to trouble
• Download software only from a trusted website and never download software’s    through email attachment as most organizations do not send them via email attachment.
• Though the software is downloaded from trusted site, scan the downloaded part, before installing it in to the system.

• Computers have a tendency to go wrong from time to time, these days total hard drive failure is rare but it does happen.
• The average home user will probably just have to back up any important files as and when they are changed, and do a full back-up once a week/month
• Keep the backups in two separate locations, so if disaster strikes one area, you still have your other backup.
• In order to back up files and folders, you must be logged on to the computer as an administrator or as a user who is part of the Administrators group.
   

• Be careful while downloading attachments from emails to your hard disk. Scan the attachment with an updated anti virus software before saving it.
• Be careful while exchanging the files between the systems through disks or through network.
• While using the disk makes sure that it is write protected, so that it prevents from accidental deletion and changes made to the files on the disk.
• Take backup of important files. This will help you in recovering the files
• Install file sharing (P2P software) carefully so that what files or Directory you are sharing and what’s being shared to other systems in P2P network.
• Use file sharing program controls and adjust the P2P program to run whenever you required. Disable automatic starting.

• Although chat rooms offer a convenient way to communicate, there are dangers which the users should be aware of
• When in a chat room or instant messaging, people may lie about their identity, which results in the accounts compromised
• Users may forget to log out, or account information may be shared by multiple parties
   

• Check the default settings in your chat software and adjust them if they are too permissive.
• Make sure to disable the automatic downloads. Take advantage of chat software that offers the ability to limit interactions to only certain users.
• Keep software up to date and this includes the chat software, your browser, your operating system, your mail client, and, especially, your anti-virus software.

• Authorizations are different in that they grant the right to see the online status of the other party
• You need to place your friends into the contact list of both computers
• Make sure that your authorization is required for people to add you to their contact lists. Someone who’s found you in white pages will almost certainly try the people who don’t require authorization first
• Make sure that the Web aware option is off particularly useful if you have some people on your invisible list
   

• Children, especially teens, love to use the chat rooms.
• Children need to be aware that people in chat rooms are strangers, and may not be honest guys.
• The privacy policy may not protect information you disclose to the others via a chat.
• Never say anything in a chat about our personal information, like your name, home address, school address etc.
