Data exfiltration is a form of security breach that occurs when an organisations data is copied, transferred or retrieved from a computer or server without authorisation. Data exfiltration can be difficult to detect, as it is often the last stage of a cyber security attack, once compromised the malware orchestrating the attack can lay dormant until the point of data exfiltration or it can take data little by little over time. It can do this because it involves the transfer or moving of data within and outside a network, which closely resembles or mimics typical network traffic, allowing substantial data loss incidents to fly under the radar.
As we celebrate International Women’s Day, we have chosen to honour two women who were vital to the design and development of Intrusion Detection Systems (IDS). Dorothy E. Denning and Rebecca Base were information security experts and pioneers who both played significant roles in the development of IDS.
Any business of any size is reliant on their ability to protect and secure their technology, data and networks from the many threats that they face. Intrusion Detection Systems (IDS) are and have been an integral part of this defense system. The aim of deploying an IDS into a network is to be able to identify if something untoward is happening and hopefully to be able to trap and remediate a problem sooner rather than later.
Everyone in the infosec community will agree that Intrusion Detection Systems (IDS) are an important component in any effective cyber security strategy, perhaps not the most press worthy but integral to policing your network borders. Much like a burglar alarm, an IDS is timeless in its effectiveness in detecting and alerting that someone has breached perimeter security measures. However, IDS technology is not evolving at the pace it once did but that doesn’t mean that there aren’t exciting innovations and changes happening.
