  1. 1. Security Measures (Biometrics, Authentication)<br />Data Backup, Cryptography, Antivirus, <br />Anti-Spyware, Firewall, <br />Human Aspects<br />
  2. 2. Data Backup<br />Data Backup is a program of file duplication. <br />Backups of data applications are necessary so that they can be recovered in case of an emergency.<br />Depending on the importance of the information, daily, weekly or biweekly backups from a hard disk can be performed.<br />
  3. 3. Cryptography<br />Cryptography is a process of hiding information by altering the actual information into different representation, for example, an APA can be written as I? X.<br />Almost all cryptosystems depend on a key such as a password like the numbers or a phrase that can be used to encrypt or decrypt a message.<br />The traditional type of cryptosystem used on a computer network is called symmetric secret key system.<br />
  4. 4. Antivirus<br />An antivirus program protects a computer against viruses by identifying and removing any computer viruses found in computer memory, on storage media or incoming e-mail files.<br />An antivirus program scans for programs that attempt to modify the boot program, the operating system and other programs that normally are read from but not modified.<br />
  5. 5. Identifying Virus<br />Two technique are used to identify the virus.<br />
  6. 6. If an antivirus program identifies an infected file, it attempts to remove its virus, worm or Trojan horse. If the antivirus program cannot remove the infection, it often quarantines the infected file. Quarantine is a separated area of a hard disk that holds the infected file until the infection can be removed. This step ensures other files will not become infected. Patents inventions Utility, design or a plant patents that protect inventions and improvements to existing inventions.<br />

  8. 8. Firewall<br />Firewall is a piece of hardware or software which functions in a networked environment to prevent some communications forbidden bye the security policy.<br />Firewall implement a security policy. It might permit limited access from in or outside the network perimeters or from certain user or for certain activities.<br />
  9. 9. Type Of Firewall<br />
  10. 10. Human Aspects Of Security Measures<br />Human aspects refer to the user and also the intruder of a computer system.<br />It is one of the hardest aspects to give protection to.<br />The most common problem is the lack of achieving a good information security procedur<br />
