smart security vs internet security

The CentOS server is supported by many netizens. How to set the security of the CentOS server? Next, let's talk about centos6's security settings from the following aspects: System security record files, startup and login security, network access restriction (centos network configuration), and prevention of CentOS atta

LinuxAndSolarisIs another two commonServer. Like Freebsd, Linux is a free operating system. They all use the GNU (a great organization) Utility set. Linux is easy to use, but not as simple as Freebsd. Solaris is SUN's commercial operating system. Articles about SUNOS are posted on the Internet, but unfortunately it does not look fast and you must patch it frequently. Let's take a look at the security config

Preface I recently read Web intrusion Security Testing and countermeasures, and have gained a lot of inspiration. This book introduces a lot of Web intrusion ideas and well-known security sites outside China, which has broadened my horizons. Here, I have summarized the attack modes mentioned in the book again, and attached some relevant references, hoping to help Web developers and

be passed to the database: Select count (*) as ctr from users where username = 'foo' and password = '\' or \ '1 \ '= \ '1' limit 1" There is nothing in the database that matches this password. Simply taking a simple step blocks a major vulnerability in a Web application. The experience here is that user input for SQL queries should always be escaped. However, several security vulnerabilities need to be blocked. The next item is to manipulate the GET

mysql_real_escape_string () as the package for user input can avoid any malicious SQL injection in user input. If you try to pass a malformed password through SQL injection, the following query will be passed to the database: Reference content is as follows: Select count (*) as ctr from users where username = 'foo' And password = ''or '1' = '1' limit 1" There is nothing in the database that matches this password. Simply taking a simple step blocks a major vulnerability in a Web application. The

Trojans or detection activities to enhance the security of your network. For example, blocking port 139 and port 445 (TCP and UDP) makes it more difficult for hackers to attack your network. Blocking ports 31337 (TCP and UDP) makes it more difficult for the Back Orifice Trojan program to attack your network. This work should be determined in the network planning phase. At this time, the security level requ

No matter how much effort we make, end users and even the IT department of the enterprise still ignore the security lapses that could have been easily corrected. This article will discuss 10 safety lapses that can be avoided and tell you how to correct this negligence. 1: Use a weak password There was a time when some people were smart to use "password" as a password to fool hackers and other malicious el

Human society is always moving forward in the constant struggle of evil forces. There is always a way to effectively prevent hacker intrusion and protect your computer systems. To establish a computer security system, enterprises should also select the security level based

With the development of technology, wireless Internet technology is becoming more and more mature and common, and Wifi coverage is also growing. One thing I like to do over the weekend is to come to the coffee shop and make a cup of coffee, turn on Windows 7, connect to Wi-Fi, and enjoy the Internet world.Wi-Fi is a technology that can connect PCs, handheld devices (such as PDAs and mobile phones) to each o

Provides simple functions, such as restrictions on port and IP access or interception. In the future, cloud computing development should provide more abundant and useful firewalls. Of course, no technology can be omnipote
