Today, foreign media (the Register) reported that there was a huge design flaw in Intel's chips, and that Microsoft and Linux kernel developers were scrambling to fix it. Security vulnerabilities will eventually be fixed, but patches will slow down the PC (and MAC) chip speed. We don't know what the speed is going to be, but one developer says a 5% spin down is common-at least on Linux-and some tasks may slow down by as much as 30%. 　　What's going on?

vulnerabilities based on the information they collect and choose the best attack method for the selected target system. Denial of service attacks: Typically, hackers target specific systems and break into systems for specific purposes. The host security of those systems often prevents attackers from gaining control over the host. However, when a denial-of-service attack occurs, the attacker does not have to gain control over the system. The goal is t

mysql| Security | Security vulnerabilities all versions of MySQL less than 3.23.31 have a buffer overflow vulnerability that causes MySQL to crash. Allows attackers to gain mysqld privileges, and can manipulate all databases. The premise of the attack is that you must have a valid login name and password. The following is a summary of the letters originally published in the MySQL mailing list. ================================================== T

SNMP (such as the Internet router), first make sure that the devices have the appropriate patches installed. £ Note that this type of SNMP vulnerability is not the only hardware device. This vulnerability also exists in Windows (excluding XP), Linux, some versions of UNIX, some mail servers and commercial servers, and some management tools including HP OpenView and CA Unicenter. This means that if you are using network management tools to monitor and control your network, you may have to use ma

SQL injection attack (SQL injection) is an attacker submitting a carefully constructed SQL statement in a form, altering the original SQL statement, and causing a SQL injection attack if the Web program does not check the submitted data. General steps for SQL injection attacks: 1, the attacker to access the site with SQL injection vulnerabilities, looking for injection point 2, the attacker constructs injection statements, injection statements and

, the value of name and PWD will change, so let's take a look at this SQL statement: SELECT * from Users WHERE UserName = ' or ' 1 ' = ' 1 ' and userpwd = ' or ' 1 ' = ' 1 ' This can be directly traced to the record, it will naturally login successfully, such a program is simply undefended: And, of course, there are many ways SQL injection vulnerabilities, we are not here in detail, our theme is how to.

Earlier, IEEE's Security Privacy published an article titled Understanding Cloud Computing Vulnerabilities. Recently translated by InfoQ into Chinese, it is reproduced as follows:Discussions on cloud computing security often fail to differentiate general and cloud computing-specific issues. In order to make the discussion on security vulnerabilities clearer, the author has developed some indicators based o

The purpose of this article is to summarize some things, solve the problem in the process of trying to construct a vulnerability database, that is how to classify the computer network vulnerabilities. Some of the ideas in this article are not mature, some even themselves are not satisfied with the right to make a point, in order to have in-depth research in this respect tongren exchanges, and improve the common.

When many technical vulnerabilities in Windows are damaged, the security of Internet cafes is threatened by the technical vulnerabilities in Internet cafes. The Internet cafe application environment involves not only the operating system, but also the network, online games, and billing management software. This also makes the Internet cafe application environment numerous technical

What have the white hat dug this year? Count the vulnerabilities that affect the world in 2015. 2015 is a year of cyber security: countless critical vulnerabilities are discovered, repaired, or exploited... Fortunately, with the efforts of White Hat hackers around the world, many fatal vulnerabilities have been fixed by the vendor before the attackers find them.F

The openness of the Internet makes Web systems face the threat of intrusion attacks, and building a secure Web system has always been the goal of people. A practical method is to establish a relatively easy-to-implement relatively secure system and establish a corresponding security auxiliary system according to certain security policies. Vulnerability scanner is such a type of security auxiliary system.Vulnerability scanning is used to detect the security of computer systems or other network de

into the building or pose security threats to the building. This is a vulnerability. For the system, for security reasons, the existence of the vulnerability must be minimized, because it will become the entry point for intruders to intrude into the system and implant malware, it affects the vital interests of our system users. Each vulnerability is different, but it can be divided into local vulnerabilities and Remote

There are two types of Software defects that cause security problems: Deployment vulnerabilities and design defects. Most of the current focus in the software security market is on discovering and fixing vulnerabilities, mainly because the automated code review tool makes the process very simple. In fact, defects in software design and architecture also account for a large proportion, which accounts for 50%
