ftp security risks

When we use the tcp ip protocol for transmission management, many of its protocols have more or less security problems. Now let's take a look at the security issues related to the FTP File Transfer Protocol. In this case, we hope you can clarify the principles in this regard. 1. FTP Port Mode The

= Filereader.readblock (thebuffer,0,1000);Filedetail.text + = new String (thebuffer,0,nread);Close this StreamReader and release all system resources associated with itFilereader.close ();So far, we have implemented a simple Web page Server Disk Management application that can view, delete directories and files. If you need to modify the files, new files and folders, and so on, just a little change, add the appropriate code on it. Since we are only using this program to describe the

More than half of AJAX security risks come from vulnerabilities hidden on the server. Obviously, the good design using secure coding technology is helpful for more secure AJAX. We need to thank Max for being familiar with the Open Web Application Security Project-OWASP) the top 10 most serious web Application Security

the Times ". Driven by Ajax bugs, Max uptime, the main web developer, decided to use Ajax in combination to create such an application. In this way, he is at the forefront of the times. Ajax Problems More than half of Ajax security risks come from vulnerabilities hidden on the server. Obviously, the good design using secure coding technology is helpful for more secure Ajax. We need to thank Max for being f

the intelligent agent for the Oracle System (Intelligent Agent), and the user's default password is also " Dbsnmp ". If you forget to modify the user's password, anyone can access the database system through that user. Now let's take a look at what permissions and roles the user has and then analyze the user's potential loss to the database system.Start the Sql/plus program and use the user login to enter:SQL>select * from session_privs;CREATE SESSIONALTER SESSIONUNLIMITED TABLESPACECREATE TABL

Attackers can obtain the main site shell and affect the Intranet and all database information. After several tests on white hats, we found that the ickey Security improve

intercepted, even if the security software such as tcp_wrapper is installed, the administrator will be "borrowed" from the file system on the NIS Server without knowing it, and cause/etc/passwd outflow. 13. send an E-mail to the anonymous account, obtain the/etc/passwd password file from the FTP site, or directly download the passwd file in the FTP site/etc dire

Hacker goes online through the intermediate host and finds the target to avoid being caught by Reverse lookup. 11. There are several methods for Hacker to access the host. You can access the host through Telnet (Port 23), Sendmail (Port25), FTP (Port 21), or WWW (Port 80. Although a host has only one address, it may carry out multi

With the popularization and importance of security education, especially the security education, anti-virus software and personal firewall are strictly required for personal computers. The virus library and system vulnerability patches are also updated in a timely manner. For most computers, the risks of computer system secur
