容器镜像漏洞扫描#
使用Trivy扫描容器镜像漏洞：
# 安装Trivy
curl -sfL https://raw.githubusercontent.com/aquasecurity/trivy/main/contrib/install.sh | sh -s -- -b /usr/local/bin
# 扫描容器镜像
trivy image ubuntu:20.04
# 扫描本地镜像
trivy image local:ubuntu:20.04
# 扫描指定严重级别的漏洞
trivy image --severity HIGH,CRITICAL ubuntu:20.04
# 生成扫描报告
trivy image --format json --output report.json ubuntu:20.04容器运行时扫描#
扫描运行中的容器：
# 扫描运行中的容器
trivy container running_container_name
# 扫描所有运行中的容器
docker ps --format "{{.Names}}" | xargs -I {} trivy container {}
# 扫描指定容器的文件系统
trivy filesystem /var/lib/docker/containers/container_id/容器配置安全检查#
使用Docker Bench检查容器配置安全：
# 运行Docker Bench
docker run --rm --net host --pid host --userns host --cap-add audit_control \
-e DOCKER_CONTENT_TRUST=$DOCKER_CONTENT_TRUST \
-v /var/lib:/var/lib \
-v /var/run/docker.sock:/var/run/docker.sock \
-v /usr/lib/systemd:/usr/lib/systemd \
-v /etc:/etc --label docker_bench_security \
docker/docker-bench-security
# 查看检查结果
# 结果会显示每个检查项的状态：PASS, WARN, INFO, NOTE初级使用#
Kubernetes集群扫描#
使用Kube-bench扫描Kubernetes集群安全：
# 运行Kube-bench
kubectl apply -f https://raw.githubusercontent.com/aquasecurity/kube-bench/main/job.yaml
# 查看扫描结果
kubectl logs -l app=kube-bench
# 扫描特定节点
kubectl get nodes
kubectl label node node_name kube-bench=scan
kubectl apply -f https://raw.githubusercontent.com/aquasecurity/kube-bench/main/job-node.yaml容器镜像深度扫描#
使用Clair扫描容器镜像：
# 安装Clair
docker run -d --name clair-db postgres:9.6
docker run -p 6060-6061:6060-6061 --link clair-db:postgres -d --name clair quay.io/coreos/clair
# 扫描容器镜像
docker pull ubuntu:20.04
docker save ubuntu:20.04 > ubuntu.tar
clairctl analyze ubuntu.tar
clairctl report ubuntu.tar容器网络配置扫描#
扫描容器网络配置：
# 检查容器网络配置
docker network ls
docker network inspect bridge
# 检查容器网络连接
docker exec -it container_name /bin/bash
netstat -tulpn
# 检查容器网络隔离
docker inspect container_name | grep NetworkMode中级使用#
容器镜像供应链扫描#
扫描容器镜像供应链：
# 使用Grype扫描镜像供应链
grype ubuntu:20.04
# 扫描镜像tar文件
docker save ubuntu:20.04 > ubuntu.tar
grype file:ubuntu.tar
# 生成供应链报告
grype --output json ubuntu:20.04 > supply-chain-report.json容器运行时安全监控#
使用Falco监控容器运行时安全：
# 安装Falco
curl -s https://falco.org/repo/falcosecurity-packages.asc | apt-key add -
curl -s -o /etc/apt/sources.list.d/falco.list https://falco.org/repo/falcosecurity-$(. /etc/os-release && echo $ID).list
apt-get update -y
apt-get install -y falco
# 启动Falco
falco
# 查看Falco事件
falco -r /etc/falco/falco_rules.yaml容器合规性扫描#
使用Open Policy Agent进行容器合规性扫描：
# 安装OPA
curl -L -o opa https://openpolicyagent.org/downloads/latest/opa_linux_amd64
chmod +x opa
mv opa /usr/local/bin/
# 创建OPA策略
cat > container_policy.rego <<EOF
package container.security
deny[msg] {
input.container.privileged == true
msg := "Container is privileged"
}
deny[msg] {
input.container.host_ipc == true
msg := "Container uses host IPC namespace"
}
EOF
# 评估容器配置
opa eval -d container_policy.rego "data.container.security" --input container_config.json中上级使用#
