本文详细介绍了Linux操作系统的安全防护软件配置,阐述了安全防护软件的配置要求,旨在提升Linux系统的安全性,确保系统稳定运行。

本文目录导读:

  1. 防火墙配置
  2. 安全防护软件配置

随着信息化时代的到来,网络安全问题日益凸显,尤其是Linux系统作为服务器操作系统的广泛应用,其安全性显得尤为重要,本文将详细介绍Linux系统安全防护软件的配置方法,帮助用户构建更加安全的操作系统环境。

防火墙配置

1、使用iptables

iptables是Linux系统中最为常用的防火墙软件,可以通过规则控制网络流量的进出。

(1)安装iptables

sudo apt-get install iptables

(2)配置iptables规则

编辑规则文件:

sudo vi /etc/iptables/rules.v4

添加以规则:

*nat
:PREROUTING ACCEPT [0:0]
:POSTROUTING ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
COMMIT
*mangle
:PREROUTING ACCEPT [0:0]
:POSTROUTING ACCEPT [0:0]
:OUTPUT ACCEPT [0:0]
COMMIT
*filter
:INPUT DROP [0:0]
:FORWARD DROP [0:0]
:OUTPUT ACCEPT [0:0]
-A INPUT -i lo -j ACCEPT
-A INPUT -p icmp -j ACCEPT
-A INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT
-A INPUT -p tcp --dport 22 -j ACCEPT
-A INPUT -p tcp --dport 80 -j ACCEPT
-A INPUT -p tcp --dport 443 -j ACCEPT
COMMIT

重启iptables服务:

sudo systemctl restart iptables

2、使用firewalld

firewalld是iptables的替代品,提供了更简单的防火墙配置方法。

(1)安装firewalld

sudo apt-get install firewalld

(2)启动firewalld服务

sudo systemctl start firewalld

(3)配置firewalld规则

添加以下规则:

sudo firewall-cmd --permanent --zone=public --add-port=22/tcp
sudo firewall-cmd --permanent --zone=public --add-port=80/tcp
sudo firewall-cmd --permanent --zone=public --add-port=443/tcp

重启firewalld服务:

sudo systemctl restart firewalld

安全防护软件配置

1、安装SELinux

SELinux(Security-Enhanced Linux)是一种强制访问控制安全系统,可以提高Linux系统的安全性。

(1)安装SELinux

sudo apt-get install selinux-basics selinux-policy-default

(2)配置SELinux

编辑配置文件:

sudo vi /etc/selinux/config

SELINUX设置为enforcing

SELINUX=enforcing

重启系统使配置生效。

2、安装AppArmor

AppArmor(Application Armor)是一种基于应用的访问控制安全系统,可以为系统中的应用程序提供额外的安全防护。

(1)安装AppArmor

sudo apt-get install apparmor apparmor-utils

(2)启动AppArmor服务

sudo systemctl start apparmor

(3)配置AppArmor

编辑配置文件:

sudo vi /etc/apparmor.d/local

添加以下内容:

#include <tunables/global>
/tunables/global/
{
    # Include the default profile
    include <tunables/global getDefault>
    # Define the default profile for the system
    profile system_default / {
        # Include the default profile
        include <tunables/global system_default>
        # Allow all files to be read
        file,
    }
}

重启AppArmor服务:

sudo systemctl restart apparmor

3、安装ClamAV

ClamAV是一款开源的病毒扫描工具,可以检测并清除病毒、木马等恶意软件。

(1)安装ClamAV

sudo apt-get install clamav clamav-daemon

(2)更新病毒库

sudo freshclam

(3)配置ClamAV

编辑配置文件:

sudo vi /etc/clamav/clamd.conf

修改以下内容:

Example
#LocalSocket /var/run/clamd.sock
LocalSocket /var/run/clamd.sock
#TCPAddr 127.0.0.1
TCPAddr 0.0.0.0
#TCPPort 3310
