Information Assurance

Better Services at Reduced Cost and Risk

The drive for greater efficiency in the provision of public services means that ever greater amounts of data will need to be shared. It is essential that the public retains confidence in the confidentiality, integrity and availability of this data if electronic public services are to be taken up and trusted by the citizen. This is true whether the service is provided online, or is part of the wider government business agenda.

Rules based tools, such as anti-virus, Intruder Detection, Firewalls and Audit Logs are established as an essential element of any Information Assurance regime, however, they are now faced with increasingly sophisticated attackers who can understand and circumvent the rules. Against these attacks analytical monitoring can provide a step change in countering the threat, providing a complete new layer to the Defence in Depth approach.

Rules based tools work by assessing the current configuration of the system against a defined baseline and raise alerts when the system goes outside pre-defined parameters. However, they suffer from two major weaknesses.

1. Being rules based, a sophisticated and experienced attacker can design an attack to avoid tripping the alarms.
2. They are very labour intensive to keep constantly up to date.

Analytical monitoring takes a different approach, analysing the behaviours within the system, building a picture of 'normal' behaviour and looking for anomalies. By constantly refining the parameters of 'normal' behaviours, it can move dynamically with changes in organisational structures and business processes. This means that it can find not only suspicious 'outlying' behaviour, but can detect anomalous behaviours that sophisticated attackers may try to hide 'within the crowd'. This makes analytical monitoring especially useful in the fight against Advanced Persistent Threats.


How SAS can help

  • Predict Data Breaches before they occur – Identify emerging trends and patterns of behaviour likely to lead to data leakage
  • Insider Threat – Detect suspicious behaviours in those with authorised system access, which may indicate abuse of privilege
  • Advanced Persistent Threats – Detect suspicious behaviours suggestive of unauthorised system access
  • Fraud – Detect anomalous actions suggestive of fraudulent behaviour by individuals, or partnerships of internal/external players
  • Error and Bad Practice – Identify patterns in individual or departmental behaviours indicating an increased risk of data leakage
