One major cause of data breaches is the stolen password. Once hackers have an email address and password, a world of possibilities are open to them. The dangers are not just limited to the account they have access to. Their hacker’s next steps usually include not only selling the details to other criminals but also “credential stuffing”; taking the login details for one account and trying it on others. Imagine if your ISP account was hacked – your work email, online shopping and other accounts most people possess would be targeted.
Companies would do well to introduce Two Factor or Multi-Factor Authentication to protect their employee and customer digital identities. Put simply, this requires another authentication criteria to be satisfied before granting access to a site or account. Many large corporates are turning to 2FA to help derisk their customer’s exposure to a data theft. Sony Playstation, Apple, Instagram, and Gmail all offer this additional security measure.

Anyone who has read the recent news of Yahoo’s data breach which affected around 500 million accounts will probably have questioned their own organization’s ability to defend itself against external attacks of all sorts.
The task of maintaining defences in the face of constant threats is often partly owned by two IT security groups, the “red”and “blue” team.:
Red: focused on testing the effectiveness of the organization by acting as hackers, using penetration testing techniques to identify and expose vulnerabilities. They will use offensive tools and use SQL injection, scan the network and be familiar with firewall and router commands.
Blue: take the role of defending the organisation, being constantly vigilant and ready to respond to any attacks. They will be expected to recognize unusual patterns, behaviours or outliers, and establish how and where attacks are about to take place. The blue team monitors the systems such as the central log file management system and scans this for signs of attempted entry.
Whilst this role playing is a familiar exercise, there are potentially dangers if the approach is not regularly reviewed:
- Regular rotation: it is recommened to switch parts of each group g. 50% change sides on a frequent basis. This improves cross-team skills and also creates a view on how „the other half think“.
- Full debriefs: after each game play has taken place, each team should explain and document how they were successful (either in attacking or defending), so learnings are formalised and captured.
- Continuous learning: funds and time permitting, create an education budget for each team member where they can choose to attend a conference, external course or online learning and increase their knowledge base. It demonstrates investment in talent and also assists team morale.
- Incentivise: introduce a trophy that is passed between teams (e.g. for not being hacked this quarter/half year etc), with the red and blue team exchanging ownership based on which was successful in the last role play.
- Review the team composition: typically in a team of 10 people, three would be responsible for IT Sec Engineering, 5-7 would take a SecOps/Incident response (usually outsourced) role, and two would act as pen testers. How does your team’s make-up look?
- Explore 3rd party participation: a real attacker doesn’t play by the rules or follow established thinking, and is going to overlook any rule, etiquette, company guidelines and ethical issues. Sometimes a genuine outsider approach is needed that does the unexpected, not permitted, daring or simply blindsides the blue team.
FOXMOLE’s penetration testing team has extensive experience in responsibly attacking client sites to identify weaknesses, whether based on an open brief or a speciifc area of concern.
The greatest opportunity offered by commissioning an external group is the discovery of pervasive, underlying vulnerabilities that have not been addressed as these were simply not on the radar. Remedial action plans can be developed in conjunction with clients, with scheduled progress review points.
