Step Four: Develop Actionable Remediations The final piece of the puzzle is to create clear remediation guidance that all teams can understand. AD administrators or IAM team members will likely implement any changes to AD. They have different priorities than the security team, and they’re under extreme pressure to maintain the backbone of the enterprise. Therefore, they need to consider how any changes to AD will affect the user's ability to do their jobs. That means any remediation recommendations need to clearly explain what the AD admins should do, the side effects of the change, and how the fix will affect overall risk exposure. This lets AD admins, executives, and management make informed decisions about executing the change. For example, remediation could break legacy application functionality. As a result, the change may need to be logged for a substantial amount of time before the organization feels confident that it won’t cripple a critical business function. Active Directory has existed for over 20 years. Unfortunately, 20 years without visibility into how privileges are applied leads to seemingly insurmountable challenges. To make real progress, teams must use other methods to evaluate their AD environment, measure risk, and give practical, actionable guidance for fixing problems. Any plan that can account for all these elements will be a massive step towards a more secure AD environment for everyone.

Surviving The New Era of Terabit-Class DDoS Attacks By Richard Hummel, Threat Intelligence Lead, NETSCOUTy In March 2018, a massive Distributed Denial of Service (DDoS) disrupted service for the developer platform GitHub. The attack, which lasted for approximately 20 minutes, was the largest on record. It was also a milestone. At roughly 1.2 terabits for second, it formally inaugurated the era of terabit-class attacks, roughly the equivalent of 25 or 30 high definition movies every second. It was followed one week later by another attack, a 1.7 Tbps assault at a U.S.-based service provider. DDoS attacks flood targeted networks with requests for traffic that overwhelm the system and cause outages. Attackers had been, for years, setting new records in the volume of traffic they could send. Still, in the years leading up to the attack, there were some that debated whether an attack of that size was even feasible given certain technical limitations. Now, just three years later, terabit-class attacks occur nearly every month. Recently, a major international enterprise software provider said that it had mitigated a 2.4 Tbps attack. The good news is that organizations with up-to-date DDoS defenses and sufficient mitigation capacity can maintain availability in the face of these extremely large attacks. But, that doesn’t mean enterprises can ignore the risk of massive DDoS attacks. Cybercriminals continue to innovate in this field by combining volumetric DDoS attacks with other threats, such as ransomware; or by deploying multi-vector attacks that drastically increase complexity for defenders.
