With the rapid development of big data, mobile Internet, cloud computing, Internet of Things and other new technologies, the amount of data and liquidity increase, operation and maintenance are faced with increased pressure on network security. In the complex network environment, attackers use system security vulnerabilities to carry out virus extortion and attack, threatening the system, information transmission, information content and network security.

What are the common network security threats to o&M?

1.DOS/DDOS

DOS/DDOS attacks the defects of network protocol implementation deliberately or directly depletes the resources of the attacked object by brutal means, causing the service system to stop responding or even crash. Computers or networks cannot accept requests from the outside world.

2. The buffer overflows

Buffer overflow attacks are attacks that exploit buffer overflow vulnerabilities to obtain system privileges. Buffer overflows can cause program crashes, system shutdowns, reboots, and more.

3. Port scanning attacks

Port scanning attack is a common detection technology. The attacker sends a group of port scanning messages to the target computer to explore the weakness and attempt to invade.

4. Virus transmission

Virus is an attacker using the inherent vulnerability of the target computer software and hardware to compile a set of instructions or program code, lurking in the storage medium (or program), when activated, infection of other programs, the destruction of computer resources. After poisoning, the usual performance is: add, delete, change, move.

5. Trojan horse attacks

A Trojan is a piece of malicious code with special functions, hidden in normal programs by looking for a back door in a computer. An attacker remotely controls computer programs through Trojan horses to monitor, destroy and delete files, send passwords, record keyboards and DOS attacks on the target computer.

6. IP spoofing

IP address spoofing is the use of IP packets to forge the source IP address, so as to impersonate the identity of other systems or senders, obtain the trust of the target computer, send malicious requests, obtain confidential information, or attack the target system without identifying the attack source.

7. The ARP deception

ARP spoofing is used to deceive the gateway MAC address of the PC on the LAN so that the PC mistakenly thinks that the changed MAC address is the gateway MAC address, causing network failure.

In the face of the above threats, how can O&M build security DAMS and prevent security risks through intelligent network security management?

Cloud Helper, through the “end + cloud + service”, ensures that every link is well executed and there is a corresponding mechanism to deal with it at every level.
