What is the biggest threat to information security?

The biggest threat to information security is "man-made threat".

Man-made threats mainly include two types:

1, unconscious threat

Unconscious threats generally refer to information leakage or destruction caused by management and user operation errors. For example, the administrator's improper security configuration leads to security loopholes, and users' security awareness is weak, so they lend their accounts to others or share them with others at will.

2. Conscious threats

Conscious threats mean that some organizations or individuals directly destroy various devices, steal and embezzle valuable data and information, create and spread viruses or change system functions for their own purposes or interests. Simply put, it is man-made malicious destruction, which can selectively destroy some information, making it lack of effectiveness and integrity, and can also obtain important information and materials through interception and decoding without affecting the normal operation of the network.

Common information security threats

1, internal leakage: due to lax internal management, internal information is intentionally leaked by internal personnel, which is the main reason for enterprise data leakage. Internet has become a great threat to enterprise information leakage. Driven by interests, employees can click the mouse, copy data and send information by email.

2. Eavesdropping: Stealing information resources and sensitive information in the system by all possible legal or illegal means. For example, monitoring the signals transmitted in communication lines, or intercepting useful information by using the electromagnetic leakage generated by communication equipment in the working process.

3. Virus infection: A computer virus is a set of computer instructions or program codes, which destroys the functions and data of the computer through self-replication, affects the normal operation of the computer, and even leads to the paralysis of the computer system. Computer viruses pose a great threat to computer systems because they are destructive.

4. Hacking attack: Hacking attack is to enter the internal network through certain technical means, attack the target host or steal sensitive information stored in it by scanning system vulnerabilities and taking advantage of weak links or system defects in system security protection. Network monitoring, denial of service, password cracking, backdoor programs, information bombs, etc. Are commonly used by hackers.
