The Role of Threat Intelligence within Your Bespoke Security Operations Centre
Threat intelligence refers to knowledge of an attacker’s activities. This can range from a simple narrative around a threat actor’s motivations all the way up to in-depth technical descriptions of an attacker’s tactics, techniques and procedures.
So, let’s ask the question: What is Threat Intelligence?
Answer: Threat intelligence is data that is collected, processed, and analysed to understand a threat actor’s motives, targets, and attack behaviours. Threat intelligence enables us to make faster, more informed, data-backed security decisions and change their behaviour from reactive to proactive in the fight against threat actors.
If you already have a Managed Outsourced IT Support Partner working within your business, then Threat Intelligence will typically be conducted by them.
The benefit to this is your Managed Outsourced IT Support Partner is already familiar with your technology, processes, and sector of business.
This means that they can employ an effective Threat Intelligence strategy that will help defend your business and your client base from cyber-attacks.
Put simply: Threat Intelligence is a key part of attempting to stay ahead, or at least, stay on par with attackers, whilst allowing you to improve your bespoke SOC and its protection levels.
The Threat Intelligence Platform
One of the tools in the armoury of your Managed Outsourced IT Support Partner as they make sure that your SOC is providing the best protection that it can offer, is using a Threat Intelligence Platform.
So, let’s ask the question: What is a Threat Intelligence Platform?
Answer: A threat intelligence platform automates the collection, aggregation, and reconciliation of external threat data, providing security teams with the most recent threat insights to reduce threat risks relevant to their organisation.
A Threat Intelligence Platform is a place for your SOC to store, correlate and manage Threat Intelligence sources and potential sources.
They are configured to analyse Threat Intelligence feeds from Threat Intelligence providers and are linked to your SIEM tool to enable automated detection of Indicators of Compromise.
There are a multitude of Threat Intelligence Platforms available on the market, so it’s important that your Managed Outsourced IT Support Partner finds a tool that works for you.
Already knowledgeable in the business sector you operate in and with your infrastructure, including hardware, firmware and software, they are in the ideal position to put the right tools to work.
Once you have a Threat Intelligence Platform in place, you’ll need to have Threat Intelligence Feeds in place that provide your SOC with the most value to identify the threats out there.
Open-source feeds provide your organisation with a range of intelligence as well as commercial feeds that provide a slightly more bespoke service.
The key parts of implementing a Threat Intelligence Platform are:
- Make sure that you don’t drown in low confidence, out-of-date Indicators of Compromise – Remember, it is very easy for attackers to change an IP address. Be wary that some threat feeds may not include “best before” dates and over time this could lead to the SOC inadvertently flagging legitimate addresses as malicious.
- Don’t underestimate the value of triaging intelligence (whitepapers, reports, news articles) – ensuring that analysts have time to read and digest intelligence reports that will lead to better understanding.
- Score intelligence according to value – If it constantly produces false positives, then perhaps review the sources you’re using.
- Make sure that your Threat Intelligence sources are providing value. It is a very competitive market, so there’s no need to put all your eggs in one basket.
So, let’s ask the question: What are Indicators of Compromise?
Answer: An Indicator of Compromise (IOC) is a piece of digital forensics that suggests that an endpoint or network may have been breached.
Just as with physical evidence, these digital clues help information security professionals identify malicious activity or security threats, such as data breaches, insider threats or malware attacks.
Unfortunately, Indicators of Compromise monitoring are reactive in nature, which means that if an organisation finds an indicator, it is almost certain that they have already been compromised.
That said, if the event is in progress, the quick detection of an Indicator of Compromise could help contain attacks earlier in the attack lifecycle, thus limiting their impact on the business.
Examples of Indicators of Compromise
What are the warning signs that the security team is looking for when investigating cyber threats and attacks? Some indicators of compromise include:
- Unusual inbound and outbound network traffic
- Geographic irregularities, such as traffic from countries or locations where the organization does not have a presence.
- Unknown applications within the system
- Unusual activity from administrator or privileged accounts, including requests for additional permissions.
- An uptick in incorrect logins or access requests that may indicate brute force attacks.
- Anomalous activity, such as an increase in database read volume.
- Large numbers of requests for the same file
- Suspicious registry or system file changes
- Unusual Domain Name Servers (DNS) requests and registry configurations
- Unauthorized settings changes, including mobile device profiles.
- Large amounts of compressed files or data bundles in incorrect or unexplained locations
