Common Computer Network Attack Knowledge

With the rapid development of the Internet, the threat to network security has become increasingly serious, with the scale and complexity of network attacks rising year by year, resulting in greater impact, it is more important to pay attention to network security issues.

The types of network attacks include:

Active attacks, which can lead to the tampering of some data streams and the generation of false data streams; these attacks can be divided into tampering, forging message data and terminals, denial of service. Passive attacks, usually including eavesdropping, traffic analysis, breaking weakly encrypted data streams, etc.

Characteristics of network attacks:

Huge losses, as the targets of attacks and intrusions are computers on the network, it will cause thousands of computers in the network to be paralyzed, causing huge economic losses to computer users.

Diverse means, covert techniques, computer attacks come in numerous forms, network attackers can obtain others' confidential information by monitoring data on the network; they can also boldly enter others' computer systems by intercepting others' accounts and passwords; they can also bypass carefully designed firewalls through some special methods, etc.

Mainly software attacks, virtually all network intrusions are carried out by intercepting and attacking software, thus breaking the entire computer system, which on one hand leads to the concealment of computer crimes and on the other hand requires people to strictly protect all sorts of computer software.

The essence of unlawful hackers' intrusion is also to scan the security capabilities of the network users' hosts, specifically targeting those hosts with low security coefficients and security vulnerabilities for intrusion. Setting traps in some websites, software download packages, and implanting viruses, waiting for users to actively click. Ordinary users may be infected with viruses when accessing these dangerous websites, downloading software or files of unknown origin, thereby being controlled by unlawful hackers, personal information may also be stolen, or even ambushed by ransomware.

It is important to do a good job in defense. If the data is encrypted due to ransomware, Shanghai Liuchan helps you recover data quickly and safely.
