Aker is a security tool that helps you configure your own Linux ssh jump/bastion host. Named after an Egyptian mythology deity who guarded the borders, Aker would act as choke point through which all your sysadmins and support staff access Linux production servers. Aker SSH gateway includes a lot of security features that would help you manage and administer thousands of Linux servers at ease. For a detailed look check our Wiki
Motivation
I couldn't find an open source tool similar to CryptoAuditor and fudo, such tools are beneficial if you're seeking becoming PCI-DSS or HIPAA compliant for example, regardless of security standards compliance access to the server should be controlled and organized in a way convenient to both traditional and cloud workloads.
Current Featuers

Requirements
Software:
- Linux (Tested on CentOS, Fedora and ubuntu)
- Python (Tested on 2.7)
- (Optional) FreeIPA, Tested on FreeIPA 4.2 & 4.3
- redis
- configparser
- urwid
- paramiko
- wcwidth
- pyte
- redis
Installation
- Automated :
- Manually:
- Aker can be setup on a FreeIPA client or indepentantly using json config file.
- Common Steps (FreeIPA or Json):
- Clone the repo
git clone https://github.com/aker-gateway/Aker.git /usr/bin/aker/- Install dependencies (adapt for Ubuntu)
yum -y install epel-release
yum -y install python2-paramiko python-configparser python-redis python-urwid python2-wcwidth redis - Set files executable perms
chmod 755 /usr/bin/aker/aker.py
chmod 755 /usr/bin/aker/akerctl.py - Setup logdir and perms
mkdir /var/log/aker
chmod 777 /var/log/aker
touch /var/log/aker/aker.log
chmod 777 /var/log/aker/aker.log - Enforce aker on all users but root, edit sshd_config
Match Group *,!root
ForceCommand /usr/bin/aker/aker.py - Restart ssh
- Restart redis
- Choosing FreeIPA:
- Assumptions:
- Aker server already enrolled to FreeIPA domain
- Create /etc/aker and copy /usr/bin/aker/aker.ini in it and edit it like below :
```
[General]
log_level = INFO
ssh_port = 22
# Identity Provider to determine the list of available hosts
# options shipped are IPA, Json. Default is IPA
idp = IPA
hosts_file = /etc/aker/hosts.json
# FreeIPA hostgroup name contatining Aker gateways
# to be excluded from hosts presented to user
gateway_group = gateways
```
- Assumptions:
- Choosing Json:
- Create /etc/aker and copy /usr/bin/aker/aker.ini in it and edit it like below :
```
[General]
log_level = INFO
ssh_port = 22
# Identity Provider to determine the list of available hosts

# FreeIPA hostgroup name contatining Aker gateways

gateway_group = gateways
