ANSWERING THE IMPORTANT QUESTION, "HAVE I BEEN HACKED?"

What Is Threat Hunting?
Cyber Threat Hunting is the process of proactively searching through networks to detect and isolate advanced threats that have infiltrated your networks by evading existing security solutions. Unlike traditional threat management measures, such as firewalls, intrusion detection systems (IDS), malware sandbox (computer security) and SIEM systems, which typically involve an investigation after there has been a warning of a potential threat or an incident has occurred – Threat Hunters actively hunt for undetected threats that may have penetrated your systems.
Threat hunting technology and processes can work with existing security infrastructure to deny attackers the ability to persist undetected. Once discovered, these threats can be quarantined and eliminated before they cause any harm, or, if the damage has already begun, the scope of the event can be limited and contained.
Cybercrime Has Gone Pro
Attackers Are Evolving on a Daily Basis
Today’s cyber criminals launch highly targeted attacks to gain valid credentials and become ‘insiders’ within your network. Once inside, they can use built-in tools and executables to accomplish their attacks, or even just sit, wait and bide their time collecting information and in some cases taking control of back up systems and internal functions.
Cyber Attacks Are Diverse
Cybersecurity Threats Can Come in a Variety of Forms.
They can come as a result of targeted attacks, environmental disruptions, and malicious activity, to even equipment failure, vulnerable third parties, and human error.
Intrusion Detection and Threat Hunting Engagement
Managed security service providers (MSSPs) generate alerts of cyber attacks, investigates and takes proactive action to mitigate and contain threats. Endpoint Sensors are deployed to allow threat hunters to collect data and perform forensic analysis to determine the overall health of the endpoint and confirm whether it is malware free.
Threat hunting assessment enables an organization to quickly and efficiently determine if any of their corporate servers and desktops have an adversarial presence on them.
Processes vary by cybersecurity agency, but to effectively “hunt” a network, they should begin with the examination 100% of IT endpoints to find:
- Signs of compromise
- The presence of persistence mechanisms used to maintain system access across reboots
- Signs of manipulation and/or hidden processes in volatile memory
- Disabled security controls
- Alterations in critical operating system files
- Unauthorized remote access tools
Defend Your System
Organizations can take active steps to defending their digital assets by levering processes and technologies, including:
- Backups and Recovery
- Access control Frameworks
- Third Party Software Patching Procedures
- Risk Based Patch Management
- Controls In Place
- Physical and Environmental Controls
- Architecture Designs
- Extend Cybersecurity Team With Third Party Experts
