Recovering From Virus Corruption
It is a sad fact that malware, such as worms, viruses and keyloggers, makes our computing experience difficult. While the responsible computer user takes steps to avoid infection, many fall victim to a malware attack at some point. Keeping anti-virus software updated, using a good firewall and avoiding risky behavior will help protect valuable data. However, mistakes are made and data becomes inaccessible.
Some malware attacks avoid discovery until the computer reboots after the infection occurs. In many cases, important system files are corrupted and rebooting to the operating system is impossible. With the operating system disabled, important files and valuable data are not available for use. However, in many cases these files can be retrieved by special file recovery software. Recovery software is usually system specific; therefore, users with Windows-based PCs must use software designed for Windows data recovery. Reading the software specifications instructs the user as to which system is used.
Furthermore, many users will panic and want to repair the system right away. Drive recovery before data recovery will damage the files, often irreparably. Most drive recoveries entail formatting the drive, which will overwrite old data. Therefore, data recovery must come first, then drive repair. Some recovery software comes with a bootable CD or DVD that contains a special operating system so that the main drive is accessible for recovery. Often it is Linux-based and bypasses the computer OS. It contains system files and the necessary hardware drivers to make recovery possible.
After booting from the emergency boot disk, file recovery saves recovered data to a secondary drive and not back to the same drive. This prevents the data from being overwritten when the infected drive is finally repaired. Secondary internal drives, external drives, CDs and DVDs are used for recovery. The choice depends on how much space the recovered files need. As a side note, the emergency disk will not become infected by the malware, as it is write-protected. Of course, the recovered data is not written to it as well.
Once that the data has been safely recovered the infected drive is repaired. A complete system restoration may be needed for repair. However, since the recovered data is safely tucked away on a different media, any repairs will not cause data loss.
The question is sometimes asked, Will data recovery software speed up my Mac or PC? In most cases, recovery software does not function as a computer optimization program. After file recovery and drive repair operations, the computer may run better. However, that comes from clearing out the junk that invariably accumulates over time. Good computer maintenance and the use of trustworthy drive maintenance software keep computers running efficiently. Of course, backing up important data is always a good idea to prevent permanent data loss.
Computer Security Authentication
Computer security is to verify the identity of a user connects to a network. Passwords, digital certificates, smart cards and biometrics can be used to prove the identity of the user to the network. Computer security includes the control message integrity, authentication, email and MAC (Message Authentication Code), check the integrity of a message. There are people of authentication, challenge-response authentication, password, digital signature, IP spoofing and biometrics.
authentication of man is the finding that the person who initiated the transaction, not the equipment. challenge-response authentication is an authentication
method used to prove the identity of a user who connects to the network. When a user connects, the access server (NAS), wireless access point or authentication server creates a challenge, usually a random number is sent to the client. The client software uses its password to encrypt the challenge with an encryption algorithm or a hash function for a path and returns the result to the network. This is the answer.
two-factor authentication requires two independent ways to establish identity and privileges. The method of using more two-factor authentication is also called strong authentication. This contrasts with traditional password authentication requires only one factor to have access to a system. Password is a secret word or code used to provide protection against unauthorized access to data. It is generally administered by the operating system or DBMS. However, a computer only to check the legality of the password, not the legality of the user.
The two main applications of digital signatures to establish a secure connection to a website and verify the integrity of the transferred files. IP spoofing refers to the inclusion of the IP address of an authorized user on the transmission of an unauthorized user to gain illegal access to a computer system.Biometrics is a more secure form of authentication password by typing or even using smart cards can be stolen. But in some respects, has a relatively high error rate. For example, fingerprints were captured by a glass of water and scanners crazy.
