As a Linux administrator, it is very important to defend against viruses, spyware, and rootkit. The following lists 10 Linux security tools. Nmap Security groupsRead the installation documentation.

On June 23, September 3, the Linux core development team published a message on the official website, indicating that the team found a hacker intrusion in 828. The hacker obtained the highest website permission root and embedded a Trojan. The Linux core development team suspected that hackers had stolen the authentication and entered the system, and then used the rootkit tool to obtain the root permission. However, it is still unclear about the method

output is enforcing, which means that the SELinux policy is already in effect.If debugging is required, you can temporarily set the SELinux mode to allow. No restart is required.# Setenforce 0After debugging, set the SELinux to mandatory mode again, without restarting.# setenforce 1LCTT: In a production environment, SELinux will certainly improve security, but it does bring a lot of trouble to application deployment and operation. Specific deployment needs to be based on the situation. ）24. Ins

1. Background On windows, applications usually use API functions to access, create, open, and read/write files. From the CreateFile/ReadFile/WriteFile function of kernel32 to the local system service, to FileSystem and Its FilterDriver, it has gone through many layers. At each layer, there are opportunities for security protection software, viruses or backdoors to monitor or filter. As security product developers, we need to go further than others, therefore, we need an underlying "windows kerne

The general method of inject is CreateRemoteThread. Today, I saw a new method in Rootkit, reminding me of the similar method I saw a year ago. Let's take a look at this method:1) the method I saw a year agoDWORD dwResult;HANDLE hThread;HANDLE hProcess;Char szDllName [] = "c: // MyDll. dll ";Int nLen = strlen (szDllName) + 1;PVOID pData = VirtualAllocEx (hProcess,NULL,NLen,MEM_COMMIT | MEM_TOP_DOWN,PAGE_READWRITE );If (param! = NULL){If (WriteProcessMe

Although a more lightweight method is provided in the kernel layer to check the integrity of key tables in the system, hibernation provides an ultimate detection method because of the anti-virus problem.According to the hiberna

Q: The server shows signs of intrusion. Ask for security settings. . Recently, my server seems to be abnormal. I often find that some programs are opened or some errors are prompted when I log on remotely. Check that the Guest account is set to admin, another account is associated with me. this should have been infiltrated. I have closed the Guest account and have any good security settings. Guest is mentioned as admin? Obviously. If the server is around, you can disconnect the network and perf

Principle and classification of no-kill There is no doubt that the "kill-free" technology is one of the hottest technologies at present. "Kill-free" is a hacker technology with high availability and wide application scope. Kill-free is often the preparation of script intrusion technology, virus attack technology, and other hacker technologies. For example, when a hacker discovers and exploits a website's Script Vulnerability, the attacker obtains the server's management permission after obtainin

SIGKILL and SIGSTOP signals cannot be captured, blocked, or ignored, but other signals can. So this is your ultimate weapon. Write a script in shell script to automate the monitoring of Chkrootkit.

RookitIntroduction: rootkit is a Linux Platform Common Trojan backdoor tool, which mainly by replacing the system files to achieve the purpose of intrusion and concealment, such Trojans than ordinary Trojan backdoor more dangerous and covert, ordinary detection tools and inspection means difficult to find this Trojan. the rootkt attack is extremely powerful and can be very damaging to the system by creating a backdoor and covert tracks through a set o

2.3.1) The main purpose of the development is to serve as the firmware interface for the next generation of computer products, instead of the widely used BIOS interface of the current PC. With the secure boot feature enabled, Windows 8 can effectively withstand low-level malware attacks, such as rootkits attacks. In an operating system with Secure boot, the system submits the digital signature of all boot components to the system's Anti-malware driver section for auditing and discovers suspicio

Each process will have a PID, and each PID will have a corresponding directory under the/proc directory, which is the implementation of Linux (current kernel 2.6) system.General backdoor procedures, in the PS and other processes to see the tool can not be found, because these common tools and even the system library in the system after the invasion has been basically passive hands and feet (the internet spread a large number of rootkit.
