What is a jump box?

A jump box is a secure computer that all admins first connect to before launching any administrative task or use as an origination point to connect to other servers or untrusted environments. Over the last few years, with malicious hackers and malware infesting nearly every enterprise network at will, security admins have been looking for a way to decrease the ability of hackers or their malware creations to steal admin credentials and take over an environment and the concept of a traditional “jump box” has morphed into an even more comprehensive and locked-down “secure admin workstation” (or SAW).

How secure are jump boxes?

Jump boxes and SAWs should have strong computer security controls applied, far stricter than would normally be applied in the regular environment. Most computer security recommendations are created in a way to enforce a moderate amount of security while at the same time being unlikely to cause any operational issues. It is difficult to apply strong security controls across a broad range of computers without causing operational issues, so most computer security baselines stop short of being highly secure. You want highly secure configurations used on jump boxes and SAWs. Some vendors offer specialized, high-security configurations, although most of the time you’ll need to create your own customized security setting. These high-security settings should be easy to apply and re-apply, and should be reapplied on a frequent basis (no less than several times a day).

What is the central tenet behind jump boxes and SAWs?

The central tenet behind both jump boxes and SAWs is that they are highly-secured computers never used for non-administrative tasks. The vast majority of computer security risk in most environments comes from administrators using the same computers for performing the highest risk activities (e.g., using email, internet browsing, office productivity apps, etc.), and possibly being compromised, and then performing administrative tasks with administrative credentials on high-risk computer systems and networks.

How long does it take for a jump box to be secure?

They should have critical security patches applied within days, not weeks.

Introduction

A jump server or jump host or jumpbox is a (special-purpose) computer on a network typically used to access devices in a separate security zone. The most common example is managing a host in a DMZ from trusted networks or computers. This could be accessing your home network from remote location.

Base Box Securing

Nowadays, deployments moved from bare metal servers to quickly started virtual machines, like the one provided by Amazon, Digital Ocean, OpenStack based providers. Thus configuration of the box no longer requires manual administration steps. At least it is overkilling in terms of time and money spent.

Optional PPTP VPN

Even if PPTP is considered weak VPN protocol, it is most easy to configure by unexperienced users. Thus usually I enable it for my clients, but enforce more strict policy for regular passwords rotation + password strength itself. For home use, I just set long enough random password + additionally protect with port knocking.

Optional OpenVPN VPN

OpenVPN is considered way stronger than PPTP, and considered to be secure for enterprise deployments. For OpenVPN, we would use in our mashup sa-vpn-openvpn role, which could be found here.

Optional SoftEther VPN

SoftEther VPN ("SoftEther" means "Software Ethernet") is one of the world's most powerful and easy-to-use multi-protocol VPN software. It runs on Windows, Linux, Mac. SoftEther VPN is open source. You can use SoftEther for any personal or commercial use for free charge.

Optional Port Knocking

Servers, by definition, are implemented as a means of providing services and making applications and resources accessible to users. However, any computer connected to the internet is inevitably targeted by malicious users and scripts hoping to take advantage of security vulnerabilities.

Using the Code

Full code in action can be found on Github here. It configures jumpbox with PPTP / OpenVPN / SSH via keys by default, but can be adjusted using option switches, to deploy set of described above combinations.
