With the birth of a series of new Internet products such as social networks and microblogs, the Web-based Internet applications are becoming more and more extensive, and enterprise information platforms are, for example, most enterprise websites, employee OA systems, and email systems are deployed on Web platforms. The rapid development of the Web has also aroused the strong attention of hackers, highlighting the Web security threats. Hackers exploit vulnerabilities in Web programs, for example,

Avoid the risk of XPath Injection-- Be aware of risks to better protect XML applications Robi Sen (rsen@department13.com), Vice President of service, Department13 With the development of simple XML APIs, Web Services, and Rich Internet Applications (RIAs), more organizations use XML as the data format in almost all aspects (from configuration files to remote process calls. Some people have used XML documents to replace more traditional plain text file

Bkjia.com exclusive translation] Alas, I miss the time when attackers were able to easily retrieve passwords. At that time, only three steps are required to defend against such attacks: first, protect your own password hashes from being stolen; second, use high-intensity passwords; third, ensure that a long password is used to avoid cracking. Nowadays, it is outdated to include passwords in the list. Today, attackers are using a clear hash

improved in the leaked tug-of-war. It was not until you used one of the following methods that you began to embark on a secure Journey: 1. whitelist. Strictly define which characters can be entered for query, and none can be entered for other characters. 2. parameterized query. Compile the SQL language and then substitute the parameters. At this time, even if he submitted select * from password where table = admin, he would only query this long strin

character list constraints, Because it's almost impossible for you to filter all the harmful inputs. If you need to accept HTML character input, it's a good idea to encode it with HTMLEncode and so on to make sure it's safe to display.
