Cyber insurance is a policy covering the financial damage of a cyber incident but is not a security measure, a financial safety net. What it covers, why it does not replace security, the controls insurers require and preparation before the policy.
Read moreSPF, DKIM and DMARC are three authentication records that prevent fake email in your domain's name. What the three do, the correct setup order, gradual DMARC tightening (none, quarantine, reject) and why to start with an audit.
Read moreA DDoS attack overwhelms a service with fake traffic to make it unreachable. How it works, DDoS types (volume, protocol, application layer), layered protection (CDN and DDoS service, scaling, rate limiting) and preparation before the attack.
Read moreRemote work moves the security boundary outside the office walls. Identity as the new boundary, two step verification, VPN and zero trust access, device and home network security, personal device policy and protecting without reducing productivity.
Read moreZero Trust is a security architecture based on never trust, always verify. Why the classic castle model no longer suffices, the three core principles (verify explicitly, least privilege, assume breach), how it is built and the gradual transition.
Read moreThe 3-2-1 backup rule is the most solid strategy against data loss: 3 copies, 2 media types, 1 offsite. The modern 3-2-1-1-0 addition (offline/immutable copy and testing), protection against ransomware and why an untested backup does not count.
Read moreA password manager stores all your passwords in an encrypted vault and generates a unique password for each account. Why it is needed, how to choose (zero knowledge architecture, encryption), how to set up, the importance of the master password and use for organizations.
Read moreAssumed breach is when a test starts not with can the attacker get in but with the attacker is already inside, what happens. Changing the assumption, why it is gaining importance, what it measures (internal defense, detection, response), its relationship with red/purple team and who it is for.
Read moreWhen you find a security flaw, what you do with it is an ethical matter. Responsible disclosure, disclosure approaches, how to prepare a proof of concept (PoC) without being destructive, ethical and legal boundaries and the security community's trust.
Read moreWhen an attacker gets in, the job does not end, it begins. Privilege escalation is rising from a limited account to admin, lateral movement is spreading across the network. How a first entry turns into a breach, defense layers and why it should be tested in a penetration test.
Read moreCTF is one of the most effective ways to learn cyber security by practicing in a safe and legal environment. What CTF is, its types (Jeopardy, Attack-Defense, King of the Hill), where to start, turning it into a career and using skill only for defense.
Read moreSAST, DAST and IAST are complementary approaches that test software security from different angles. The difference between static and dynamic analysis, human secure code review, embedding it in the process with DevSecOps and which to use when.
