Database Security - OWASP Cheat Sheet Series
Database Security Cheat Sheet¶ Introduction¶. This cheat sheet provides guidance on securely configuring and using the SQL and NoSQL databases. It is intended to be used by application developers when they are responsible for managing the databases, in the absence of a dedicated database administrator (DBA).
Why is it important to harden your database?
Your database is the jackpot that every attacker aims to capture. As attacks get more sophisticated and networks get more hostile , it’s more important than ever to take additional steps to harden your database.
Why is password manager important?
Given that most people don’t manually log into a database all that often, use a password manager or the command-line tool, pwgen, to create a random, 20-character password for your database accounts. This is important even if you use additional MySQL access control to limit where a particular account can login from (such as limiting accounts strictly to localhost).
What is an anonymous MySQL account?
Anonymous accounts are MySQL accounts that have neither a username nor a password. You don’t want an attacker to have any kind of access to your database without a password, so look for any MySQL users recorded with a blank username in the output of this command:
What happens if you don't set a password for the root user?
So if you don’t set a password for the root user, anyone who may be able to get a local shell on your MySQL machine now has complete control over your database.
What is the most important MySQL account to set a password for?
The most important MySQL account to set a password for is the root user . By default in many systems, this user will have no password.
Why is it important to use TLS?
Setting strong passwords only gets you so far if an attacker can read your password or other sensitive data as it passes over the network. Therefore, it’s more important than ever to secure all of your network traffic with TLS.
Why is database important?
These days the trend has moved toward most parts of your infrastructure being disposable and stateless, which puts an even greater burden on your database to be both reliable and secure, since all of the other servers inevitably store stateful ...
What is database hardening?
So as I understand it database hardening is a process in which you remove the vulnerabilities that result from lax con-figuration options. This can sometimes compensate for exploitable vendor bugs.
What is the meaning of "back up"?
Making statements based on opinion; back them up with references or personal experience.
What happens if you base controls on specific threats?
If you try to base controls on specific threats, you'll just end up constantly in catch-up mode.
Should you base your securing of any component of your infrastructure on specific threats?
I'd suggest that you shouldn't base your securing of any component of your infrastructure on specific threats (e.g. whatever the todays "hot 0-day" is).
What does system hardening mean?
System hardening is the process of securing a server or computer system by minimizing its attack surface, or surface of vulnerability, and potential attack vectors. It’s a form of cyberattack protection that involves closing system loopholes that cyberattackers frequently use to exploit the system and gain access to users’ sensitive data.
What is server hardening?
Server hardening is a general system hardening process that involves securing the data, ports, components, functions, and permissions of a server using advanced security measures at the hardware, firmware, and software layers. These general server security measures include, but are not limited to: ...
How does network hardening work?
Two of the main ways that network hardening is achieved are through establishing an intrusion prevention system or intrusion detection system, which are usually software-based. These applications automatically monitor and report suspicious activity in a given network and help administrators prevent unauthorized access to the network.
What is the purpose of hardening a system?
The basic purpose of implementing system hardening techniques and practices is to simply minimize the number of potential entryways an attacker could use to access your system and to do so from inception. This is oftentimes referred to as following a secure-by-design philosophy.
What is AES encryption?
Using self-encrypting drives or AES encryption to conceal and protect sensitive information. Using firmware resilience technology, memory encryption, antivirus and firewall protection, and advanced cybersecurity suites specific to your operating system, such as Titanium Linux.
Which organization maintains one of several system hardening standards?
Photo: The NIST maintains one of several system hardening standards.
How to achieve a hardened state for an operating system?
One of the best ways to achieve a hardened state for the operating system is to have updates, patches, and service packs installed automatically. OS hardening is like application hardening in that the OS is technically a form of software.
What is systems hardening?
Systems hardening is a collection of tools, techniques, and best practices to reduce vulnerability in technology applications, systems, infrastructure, firmware, and other areas. The goal of systems hardening is to reduce security risk by eliminating potential attack vectors and condensing the system’s attack surface. By removing superfluous programs, accounts functions, applications, ports, permissions, access, etc. attackers and malware have fewer opportunities to gain a foothold within your IT ecosystem.
How does hardening work?
Systems hardening recovers continuous effort, but the diligence will pay off in substantive ways across your organization via: 1 Enhanced system functionality: Since fewer programs and less functionality means there is less risk of operational issues, misconfigurations, incompatibilities, and compromise. 2 Significantly improved security: A reduced attack surface translates into a lower risk of data breaches, unauthorized access, systems hacking, or malware. 3 Simplified compliance and auditability: Fewer programs and accounts coupled with a less complex environment means auditing the environment will usually be more transparent and straightforward.
What is application hardening?
Application hardening: Remove any components or functions you do not need; restrict access to applications based on user roles and context (such as with application control); remove all sample files and default passwords. Application passwords should then be managed via an application password management/privileged password management solution, that enforces password best practices (password rotation, length, etc.). Hardening of applications should also entail inspecting integrations with other applications and systems, and removing, or reducing, unnecessary integration components and privileges.
What is network hardening?
Network hardening: Ensure your firewall is properly configured and that all rules are regularly audited; secure remote access points and users; block any unused or unneeded open network ports; disable and remove unnecessary protocols and services; implement access lists; encrypt network traffic.
How to enforce least privileges?
Eliminate unnecessary accounts and privileges: Enforce least privilege by removing unnecessary accounts (such as orphaned accounts and unused accounts) and privileges throughout your IT infrastructure.
What is attack surface?
The “attack surface” is the combination of all the potential flaws and backdoors in technology that can be exploited by hackers. These vulnerabilities can occur in multiple ways, including:
What does "simplified compliance" mean?
Simplified compliance and auditability: Fewer programs and accounts coupled with a less complex environment means auditing the environment will usually be more transparent and straightforward.
What are the steps to a regression testing environment?
Whether you have a fully integrated testing environment and CI/CD pipeline (ideal) or a fully manual and person-driven regression testing environment (least ideal), you should follow the same hardening steps: scan, remediate, test, scan, and automate.
Why should you perform regression testing?
If you don’t have integration tests (e.g., Serverspec, Testkitchen, Beaker, Selenium, etc.), you should always perform regression testing to ensure that introduced hardening doesn’t prevent required functionality.
What is the NIST?
Another widely accepted authority in the private and public sectors is the National Institute for Standards and Technology (NIST). NIST provides guidance on multiple technologies and is often the gold standard on which many other agencies base their own practices and documentation.
What happens if you get hacked?
So, you’ve been hacked. Maybe your system was modified for malicious reasons, your information was stolen, or your website was defaced. All of these scenarios cause panic. The effects of a successful breach can result in loss of revenue, customer trust, shareholder faith, sensitive data, and even your business.
Can tools be used to remediate vulnerabilities?
Tools can do that. Tools are able to scan your entire environment, build reports, give you a means to benchmark, and even remediate vulnerabilities for you. However, a word of caution: do not auto-remediate vulnerabilities in a production environment without knowing what it’ll do, and don’t do it until you’ve tested it.
Is it better to have auditors discover findings that you can resolve than it is to have an attacker exploit them?
It’s much better to have the auditors discover findings that you can resolve than it is to have an attacker exploit them .
Can an attacker scan your environment?
Remember, the worst part is not that you’ll have all the findings in your audit report — it’s that an attacker can scan your environment, find that weakness, and exploit it on all of your systems. Don’t give them the easy win; install all security patches.
System Hardening
An attack surface includes all the flaws and vulnerabilities such as default passwords, poorly configured firewalls, etc, which can be used by a hacker to gain access to a system. The idea of system hardening is to make a system more secure by reducing the attack surface present in its design.
Standards for System Hardening
System Hardening standards are the set of guidelines that are to be followed by all the deployed systems governed by them. These standards may vary from organization to organization depending on business needs, but there are certain requirements that are included in all of them.
How to perform System Hardening?
System Hardening is a complex, but necessary process to ensure system security. The process of hardening the system will vary from system to system depending on the system’s configuration and the level of complexity of the codebase.
Importance of System Hardening
System Hardening reduces the attack surface of systems thereby reducing the opportunities that a hacker may find to get access to a system prior to deployment. It increases the robustness of the system and makes it more resistant to unauthorized access by people of malicious intent.
How are permissions managed?
Permissions are managed through roles or groups, and not by direct grants to user IDs where possible . Strong passwords in the database are enforced when technically possible, and database passwords are encrypted when stored in the database or transmitted over the network.
What is protected against unauthorized access to a session?
If users are allowed protected data on their workstations, then the workstation is protected against unauthorized access to a session by deploying screen savers. Users understand the requirement to lock their workstations when leaving the station.
