Why do network security incidents occur frequently?

In recent times, network security incidents have "exploded" one after another. Now in the 18th year of the 21st century, no one can easily leave the network. Although it exists in a silent state, it has indispensable consequences. The weight of neglect. But today's online world is full of crises, undercurrents, and dangers. Ransomware viruses and online fraud are rampant, threatening the healthy development of the Internet.

In the successive outbreaks of network security incidents, the first problem was caused by Intel, the world's most well-known semiconductor manufacturing giant. This company that provides computer chips to the world was exposed to design flaws in the chips. Subsequently, Intel It was announced that a new network security department would be established. The incident was also called "the largest security incident in computer history" by some industry experts. I believe that the ransomware incident that ravaged the world in May 2017 is still unforgettable. This ransomware named "WannaCry" swept through more than 150 countries in one day. Computer users in many countries were locked by the ransomware and unable to Carry out normal work.

Threats to network security can be said to be omnipresent. By now, you've probably heard that 99% of ransomware attacks are carried out through email disguises. Maybe your friends in the IT industry will also recommend you to implement security measures such as spam filters, firewalls, anti-virus and security information and event management (SIEM) solutions. These safeguards can go a long way in preventing this kind of attack. However, there is no foolproof solution when it comes to cybersecurity.

Apple will issue patches for its products affected by a "product" flaw, after major chipmakers disclosed vulnerabilities that make nearly all modern computing devices vulnerable to hackers. Newslook has also improved on security products and product extensions (many of which are mirrors of each other at this point) as ransomware has emerged. In the world of antivirus, the latest trend is machine learning, which deviates from previous definition-based versions by using artificial intelligence to identify when a system becomes unusual. However, malware and ransomware are not the only threats to data. In fact, recent security issues aren't viruses at all. Google engineers recently discovered vulnerabilities in Intel, AMD and ARM processors that have been found in nearly every computer and smartphone over the past 20 years. The vulnerabilities, dubbed "Spectre" and "Crash", are Security flaws in the actual architecture of computer processors. This architectural flaw could render a system unexploitable if cybercriminals find a way to exploit it. In short, this vulnerability could be exploited to monitor and capture all data processed on any given device on an affected processor.

Microsoft has taken swift action to create updates for their major operating systems to address this vulnerability. Other major operating system vendors are doing the same thing, and security vendors are working around the clock to update their antivirus programs. It is understood that these updates, although required to significantly slow down the system by up to 30%, can ensure that the vulnerability has been resolved or enhance network security, so it is very important to regularly monitor your network and seek security products.

In the ransomware incident, what is surprising is that the source of the virus is actually a hacker weapon developed by the US government for Windows and other systems. This makes us realize that no matter how powerful the network protection system is, it is possible to be breached. There is no safe place in the world that is impregnable and invulnerable. No matter how sophisticated the design is and how complex the structure is, there will be loopholes without exception. A study in the field of network security shows that for every 1,000 lines of code written by programmers, 1 to 6 defects or errors will appear, and these 1 to 6 defects may produce vulnerabilities. If these vulnerabilities cannot be avoided, then "being The possibility of attack will increase.

So in the face of the new battlefield of network security, how should we maintain network security? Nowadays, the number of mobile phone users in China is very large, so the first thing we need to ensure is the network security of mobile phones. Maintain mobile phone network security, such as preventing telecommunications fraud, phone harassment, and protecting personal information. Therefore, we must install security software on our mobile phones. Of course, mobile phones now come with built-in security software. With these software, we can intercept some spam text messages, harassing phone calls, and block some malicious websites.

Since the computer system itself may have some vulnerabilities, therefore, the use of computers should enhance security awareness. Install security software, such as Computer Manager, Kingsoft Internet Security, and 360 Security Guard. These software can play a certain protective role. When the website you visit is irregular, it will remind you in time. After installing security software, be sure to use it to scan and kill viruses on your computer regularly and conduct regular physical examinations to prevent your computer from being infected by some malicious viruses. If a new virus appears, be sure to pay attention to this news in a timely manner, follow the official instructions, or have your computer protected by professionals; you can also update the computer system to fix vulnerabilities.

The massive information in the Internet era makes the information mixed, and we do not have good identification capabilities, so we should not open some unknown websites and install some software from unknown sources. In addition to the relevant protective measures designed and developed by companies for the public, the public themselves also need to strengthen their awareness of network security to avoid the leakage of personal information. Users must first ensure the security of the network usage environment, try to avoid connecting to WIFI in public places at will, and beware of falling into fake WIFI set up by criminals to collect personal information, which may put their personal and property safety at risk. It is necessary to promptly update mobile phone Trojan detection and other systems, and do not use personal passwords that will not change for thousands of years. In addition to black technology blessing network security, maintaining network security is also inseparable from the cultivation of talents. Everyone who knows how to play with computers has become a hacker, so we need to train some high-tech talents to maintain network security in order to fight against malicious attacks by hackers. The current era is our era. We should shoulder the heavy responsibility of maintaining network security and contribute our own modest efforts to maintain the network environment.
