best linux security software

Data security is one of the most important problems people use in computers. Typically, a hard disk mirroring technique is used in a server environment to achieve a dual backup of the data. Also, we can use this technology in a Linux environment. In the Linux environment, the use of raidtools tools, not only can be two hard disk mirroring, but also can make soft

who uses a PC can only make a reference.The systems mentioned in this article, if not specifically stated, all adopt redhat's redhat linux system. OptimizationSpeaking of optimization, the best optimization is to improve the hardware configuration, such as improving the cpu computing capability and memory capacity. I personally think that if you want to upgrade the hardware, we recommend that you increase the memory capacity first. generally, server

think that first, we need to clarify the point of view that security must be considered first when performing any operations on the server, upgrading or modifying any configuration file or software, it's not something new, it's better. That's why linux management feels different from windows. For windows, we recommend that you use the latest version of the

With the expansion of Linux enterprise applications, there are a large number of network servers using the Linux operating system. Linux server security can be more and more attention, here according to the depth of the attack on the Linux server in the Level form, and propo

instances will gradually become a burden. Microsoft Active Directory and Windows Server users may already be familiar with RADIUS servers and learn how to use them to implement and manage the two-factor authentication mechanism. Although this method can also be extended to Linux servers, it is extremely difficult to implement and is difficult to be widely applied to other systems that require a two-factor verification solution. In view of this, the D

Whether you are an ordinary Linux Desktop user or a system administrator managing multiple servers, you are faced with the same problem: an increasing number of threats. Linux is an open system that allows you to find many ready-made programs and tools on the network. This facilitates both users and hackers, because they can also easily find programs and tools to sneak into the

SSH is the abbreviation for secure Shell, developed by the IETF Network Working Group, and SSH is a security protocol based on the application layer and transport layer.SSH is currently a more reliable protocol that provides security for Telnet sessions and other network services. often used for remote logins, and for copying data between users. The use of SSH protocol can effectively prevent the informati

Lack or even absence of maintenance is a major factor endangering system security. 　　 One

, the best way to ensure the security of the entire system is to understand the operating principles and mechanisms of attacks, what tools are used in attacks, and how to perform intrusions. And know how to reduce risks from deploying linux. I. clues: start with the log Logs record the daily events of the system. they can be used to check the cause of the error or trace the traces left by the attacker. Th

more secure ssh instead and then kill the lnetd process. In this way, inetd no longer monitors the daemon on your machine, so that no one can use it to steal your application port. You 'd better download a port scanner to scan your system. If you find an open port that you don't know, immediately find the process using it to determine whether to close it. 　　2.

In fact, the abstract Linux operating system is not the safest operating system at all. In fact, some Linux releases intentionally do not provide comprehensive

In the operating system, if Windows is described with loopholes, the most common adjective about Linux may be "impeccable. When people are increasingly keen on finding Microsoft's operating system and software vulnerabilities, making Windows an increasingly popular target for hackers, but it often ignores the second most popular Linux operating system in the worl

1) Linux 3.13 Linus Torvalds released Linux Kernel 3.13 some time ago as the opening ceremony in 2014. By convention, this version updates a large number of drivers. In addition, Linux Kernel 3.13 includes nftable, which is the successor of the famous iptables. From the submitted code, nftables continues to use the existing netfilter hooks, Connection Tracing Sys

After installing Linux software, I will study and study how to install Linux software. I will discuss with you how to install Linux software, I hope it will be useful to you. Install and Uninstall

proliferation of Dos attacks and the fact that the defects of the protocol layer are not changed in the short term, DOS becomes the most widespread and the most difficult way to prevent attack. Denial of service attacks include distributed denial of service attacks, reflective distributed denial of service attacks, DNS distributed denial of service attacks, FTP attacks, and so on. Most service denial of attack leads to a relatively low-level risk, that is, those attacks that may cause the syste
