How to write an introduction to the network security handwritten newspaper

Network security handwritten copy:

The meaning of network security: refers to the protection of the hardware, software and data in the network system from accidental or malicious reasons. and be subject to damage, alteration or leakage.

Case of cyber attacks:

On February 4, 2012, the hacker group Anonymous released a recording of a work call between the FBI and the Metropolitan Police in the United Kingdom on January 17. , 17 minutes long, the main content is the two sides discussing how to find evidence and arrest black hat hackers such as Anonymous, LulzSec, Antisec, CSL Security, etc., while the sensitive content involving underage hackers is obscured.

The FBI has confirmed the authenticity of the call recording, and security researchers have begun to address vulnerabilities in the teleconferencing system.

On February 13, 2012, it was said that a series of government websites were attacked by the Anonymous organization, and the CIA official website was hacked for nine hours on Friday. This organization had previously intercepted a confidential telephone conversation between the London police and the FBI and subsequently uploaded it to the Internet.

Solutions when suffering from network attacks:

1. Intrusion detection system deployment

Intrusion detection capability is an important factor in measuring whether a defense system is complete and effective. A powerful and complete intrusion detection system can make up for the shortcomings of firewalls in relatively static defense. Conduct real-time detection of various behaviors from the external network and the campus network, promptly discover various possible attack attempts, and take corresponding measures. Specifically, the intrusion detection engine is connected to the central switch. The intrusion detection system integrates intrusion detection, network management and network monitoring functions. It can capture all data transmitted between internal and external networks in real time. It uses the built-in attack signature library and uses pattern matching and intelligent analysis methods to detect intrusions on the network. behaviors and abnormal phenomena, and record relevant events in the database as the basis for network administrators' subsequent analysis; if the situation is serious, the system can issue real-time alarms so that school administrators can take timely response measures. ?

2. Vulnerability Scanning System

Using the most advanced vulnerability scanning system to regularly conduct security checks on workstations, servers, switches, etc., and providing detailed and reliable security analysis reports to system administrators based on the inspection results to improve network security. The overall level produces important evidence.

Network security slogan:

1. Thunder Network, win time and win life.

2. Maintain network security and protect personal privacy.

3. Work together to build the Chinese dream and work together to build a powerful cyber nation.

4. Xunlei Technology: Service network, connecting you and me.

5. There is no pie in the sky, and there are many traps when calling from strangers.

6. Protect your password and account well, otherwise your money will suffer if it is leaked.

7. Online life, service is mine!

8. Everyone is civilized on the Internet, and everyone is civilized on the Internet.
