. Focus on the implementation of security measures for mobile devices Mobile device manufacturers are aware of the importance of mobile device security. For example, I-Pad introduces a wide range of security mechanisms, including password mechanisms, device encryption, encrypted network connections, and Remote Data erasure, this greatly improves the

Analysis of several security threats facing the medical industry in 2016 At the beginning of 2016, the medical industry suffered from many security incidents, for example, ransomware attacks at the Los Angeles Hospital, ransomware attacks at a German hospital, patient monitors and drug administration systems, and attacks at the Melbourne Hospital. In 2016, just t

The source code of the core components of the iPhone operating system has been leaked recently. Hundreds of millions of iOS devices may face security threats !, IPhone IOS Recently, the source code of the core components of the iPhone operating system has been leaked. This message is from the discovery that the iBoot source code of iOS is shared on GitHub. IBoot source code is an important component of th

Rootkit can be said to be one of the latest security threats. Anyone who has heard of it knows it is notorious: cannot be deleted, exists within a computer for several years without being discovered, and can launch an attack through the operating system. Rootkits: A hidden security threat What is rootkit? According t

over the network, dependent system: WIN9X/NT/2000/XP. After running the program, the virus will steal the user's QQ number and password and send it to the hacker, which may cause the user's personal information leakage. The virus also downloads files from the network to infected computers and terminates the running of multiple anti-virus software. As a result, these antivirus software cannot be used normally. 1 2 Next Page [Content navigat

Recently, in the PWN20WN hacker competition, the VUPEN team that previously cracked Chrome has used two different 0-day vulnerabilities to break one of them.Windows7 SP1 system computer, which means that IE9 browser was also cracked in this hacking competition. Chaouki Bekrar, the team leader, said that the 0-day vulnerability they used in IE9 is actually applicable to IE6 to IE10 browsers, this means that IE10 with WIN8 debut will face severe

security policies can greatly reduce security risks Another aspect worth reflecting on is the application of private devices in internal IT systems. The Parties mentioned above may use a private digital camera to take materials into a personal computer, or use a personal mobile hard drive to transfer data. These vulnerabilities expose the vulnerabilities that en

File System fragmentation is not a strange problem for most computer users. But in fact, they do not understand the real dangers of it. They do not know that file fragments can cause system performance degradation and speed reduction. For family users, the best performance in the game is an example. After all, this is usually the project with the highest performance requirements. Users who are aware of the dangers of File System fragments often know t

leakage of confidential information and even lead to security breakthroughs. 4. RSS/atom Injection This is a new Web2.0 attack. RSS feedback is a common means for people to share information in portals or online applications. The network application receives the feedback and sends it to the browser of the client. People can insert text Javascript in the RSS feed to attack users' browsers. When an end user

When we receive an email, we usually pay special attention to executable files to avoid viruses. But the current virus disseminators come up with a way to deal with this, that is, to disguise files. Sorry, many users think that this is just a common image, so they can open it with confidence. This is the trap of others and is infected with the upper body. In fact, many friends will say that you can set the display file extension in "Folder Options".

DNS is a naming system that converts a human-readable domain name into a computer that can recognize IP addresses. When a domain name query request that does not exist in the parser cache appears, the conversion process is from the root server to the top-level domain name, for example. com domain name) in the entire DNS hierarchy. Next, the top-level domain name (TLD) will find the authorized Domain Name Server that can provide us with the required IP

your current environment, and then the most likely culprit. The biggest enemy is not necessarily the highest ranking vulnerability. It doesn't matter. The key sorting is based on the possibility of injury. The real harm, the most likely harm in the future, is better than speculation. Understanding this should change a lot of operations as a computer security defender.Fact 4. Firewall and anti-virus softwar

In recent years, along with the development of computer networks and communication technology, it not only brings great convenience to people's lives, but also enables people to enjoy more material and culture. At the same time, network security threats are becoming more and more serious, such as hacker attacks, data theft, and virus release. Although we are also

access permissions are mainly used to address the common application security threats caused by illegal network operations of computer knowledge in statistics. Its main task is to prevent unauthorized use and access to network resources. The general practice is to strengthen inbound control, such as user name identifi

The purpose of this article is to summarize some things and solve the main problems encountered when attempting to construct a Vulnerability Database, that is, how to classify computer network vulnerabilities. Some of the ideas in this article are not mature, and some are not even satisfied with themselves, so as to communicate with colleagues who have in-depth research in this area and improve the work together.
