The Arizona Department of Homeland Security (AZDOHS) operates in an environment that requires a robust cybersecurity strategy to protect against ever-evolving threats. With a mission to safeguard state and local infrastructures, the team at AZDOHS faced the daunting task of monitoring an expansive array of data points and potential vulnerabilities.

The threat of phishing attacks looms larger than ever. The LA County Department of Public Health recently announced that 50 employees fell victim to phishing attacks, compromising sensitive patient data. These deceptive schemes have become a staple in the cyberthreat landscape, targeting individuals and businesses of all sizes. For every employee, understanding the signs and consequences of a phishing attack is crucial to safeguarding their organization.

Managing vulnerabilities can feel like the end of the first act of Les Misérables as you sing to yourself, “one day more, another day another vulnerability.” Like Jean Valjean, you attempt to put up barricades to protect your environment from attackers exploiting these security weaknesses. Keeping pace with the number of vulnerabilities and threat actor activities becomes overwhelming, leaving you to feel outnumbered and outmanned.

Every security engineer has experienced this issue: after spending a lot of time creating a new SIEM alert to catch malicious behavior, you deploy it, only to find there are over 100 service accounts triggering false positives. Your SIEM is suddenly flooded with false alerts, and your team is overwhelmed as a result. You then spend hours or even days investigating these alerts and fixing your detection rule, hoping it will work better next time.

Cloud environments today continue to grow in size and complexity, which increases the demand for improved security coverage in order to protect an organization’s assets, data, and reputation. This growth has also created significant and complex challenges in identifying insider or external threats, compromised accounts, and anomalous behavior across environments.

Bolster your organization’s observability and security capabilities on one platform with AI, anomaly detection, and enhanced attack discovery Organizations in today’s digital landscape are increasingly concerned about service availability and safeguarding their software from malicious tampering and compromise. The traditional security and observability tools often operate in silos, leading to fragmented views and delayed responses to incidents.

Phishing is the weapon of choice for many adversaries. And it’s easy to understand why: Users fall victim to attacks in under 60 seconds on average, novice cybercriminals can launch effective phishing campaigns thanks to off-the-shelf phishing kits and generative AI, and above all, it works — 71% of organizations reported at least one successful attack in 2023.

(A thought from The Matrix: Neo likely used a SIEM before he took the red pill and could see the matrix without one...) One of the best ways to monitor security-related activities for your organization is to collect audit logs from every network device and analyze those logs for activities which violate acceptable behavior. This is precisely the role of a SIEM or Security Information and Event Manager. Let me simplify your life by providing some best practice suggestions for deploying and using a SIEM.

Devo recently brought together an esteemed panel of modern CISOs to discuss the issues that matter most to them and their peers.
