本文目录导读:
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
添加以下规则:
*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
将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 TCPPort 3310 #EnableLuaScript false EnableLuaScript true #LuaSocketTimeout 10 LuaSocketTimeout 30 #AllowSupplementaryGroups false AllowSupplementaryGroups true #User clamav User clamav #Group clamav Group clamav #LogFile /var/log/clamav/clamd.log LogFile /var/log/clamav/clamd.log #LogTime true LogTime true #MaxConnectionQueue 1000 MaxConnectionQueue 1000 #MaxConnectionRequests 1000 MaxConnectionRequests 1000 #MaxFileDescriptor 4096 MaxFileDescriptor 4096 #MaxConnectionRate 100 MaxConnectionRate 100 #MaxConnectionsPerIP 100 MaxConnectionsPerIP 100 #MaxConnectionDuration 60 MaxConnectionDuration 60 #MaxStreamDepth 1000000 MaxStreamDepth 1000000 #MaxPartitions 100 MaxPartitions 100 #MaxScanSize 100M MaxScanSize 100M #MaxDirectoryEntrySize 1000000 MaxDirectoryEntrySize 1000000 #MaxScriptSize 1000000 MaxScriptSize 1000000 #Max PE sections 50 MaxPESections 50 #Max PE import addresses 10000 MaxPEImportAddresses 10000 #Max PE export addresses 10000 MaxPEExportAddresses 10000 #Max PE resources 1000 MaxPEResources 1000 #Max ELF sections 50 MaxELFSections 50 #Max ELF program headers 10 MaxELFProgramHeaders 10 #Max ELF section headers 10 MaxELFSectionHeaders 10 #Max RAR files 100 MaxRARFiles 100 #Max RAR Solid files 100 MaxRARSolidFiles 100 #Max PDF pages 1000 MaxPDFPages 1000 #Max PDF embedded files 100 MaxPDFEmbeddedFiles 100 #Max OLE objects 100 MaxOLEObjects 100 #Max OLE streams 100 MaxOLEStreams 100 #Max Cabinet files 100 MaxCabinetFiles 100 #Max Cabinet streams 100 MaxCabinetStreams 100 #Max Cabinet storage streams 100 MaxCabinetStorageStreams 100 #Max Cabinet substorage streams 100 MaxCabinetSubStorageStreams 100 #Max Cabinet properties 100 MaxCabinetProperties 100 #Max Cabinet property sizes 1000000 MaxCabinetPropertySizes 1000000 #Max Cabinet components 100 MaxCabinetComponents 100 #Max Cabinet entries 100 MaxCabinetEntries 100 #Max Cabinet streams in a file 100 MaxCabinetStreamsInAFile 100 #Max Cabinet files in a cabinet 100 MaxCabinetFilesInACabinet 100 #Max Cabinet size 100M MaxCabinetSize 100M #Max Cabinet extractable size 100M MaxCabinetExtractableSize 100M #Max Cabinet compression types 10 MaxCabinetCompressionTypes 10 #Max Cabinet cabinets in a cabinet 10 MaxCabinetCabinetsInACabinet 10 #Max Cabinet cabinet names 100 MaxCabinet CabinetNames 100 #Max Cabinet cabinet name sizes 100 MaxCabinet CabinetNameSizes 100 #Max Cabinet cabinet comment sizes 100 MaxCabinet CabinetCommentSizes 100 #Max Cabinet cabinet properties 100 MaxCabinet CabinetProperties 100 #Max Cabinet cabinet property sizes 1000000 MaxCabinet CabinetPropertySizes 1000000 #Max Cabinet cabinet components 100 MaxCabinet CabinetComponents 100 #Max Cabinet cabinet entries 100 MaxCabinet CabinetEntries 100 #Max Cabinet cabinet streams in a file 100 MaxCabinet CabinetStreamsInAFile 100 #Max Cabinet cabinet files in a cabinet 100 MaxCabinet CabinetFilesInACabinet 100 #Max Cabinet cabinet size 100M MaxCabinet CabinetSize 100M #Max Cabinet cabinet extractable size 100M MaxCabinet CabinetExtractableSize 100M #Max Cabinet cabinet compression types 10 MaxCabinet CabinetCompressionTypes 10 #Max Cabinet cabinet cabinets in a cabinet 10 MaxCabinet CabinetCabinetsInACabinet 10 #Max Cabinet cabinet cabinet names 100 MaxCabinet CabinetCabinetNames 100 #Max Cabinet cabinet name sizes 100 MaxCabinet CabinetCabinetNameSizes 100 #Max Cabinet cabinet comment sizes 100 MaxCabinet CabinetCommentSizes 100 #Max Cabinet cabinet cabinet properties 100 MaxCabinet CabinetCabinetProperties 100 #Max Cabinet cabinet property sizes 1000000 MaxCabinet CabinetPropertySizes 1000000
