IT infrastructure you can rely on, defended every day

Six ways to strengthen authentication without burdening users:

• Two-factor authentication (2FA) — A code by SMS, an authenticator app (Google Authenticator, Authy) or biometrics as the second factor.
• Biometric authentication — Fingerprint, facial or iris recognition — often more convenient than passwords.
• Behaviour-based authentication — Typing style, browsing habits and usage patterns verify identity with no extra steps.
• Multi-factor authentication — Combine a password with a token or a fingerprint for added security.
• Passwordless solutions — Security tokens, digital certificates or blockchain-based authentication, with no complex passwords to remember.
• Single sign-on (SSO) — One account or identity services such as OAuth / OpenID Connect cut the number of passwords.

Six ways blockchain technology strengthens security:

• Data security — A distributed, immutable ledger — encrypted data is hard to alter without authorisation.
• Authentication and authorisation — Digital identity managed in a decentralised way, reducing fraud and unauthorised access.
• Auditability and transparency — Immutability makes every transaction traceable and verifiable.
• Applications and smart contracts — A safe environment to automate security processes and report incidents in real time.
• Fraud prevention — Recording and verifying critical events reduces data manipulation.
• Data integrity — Verification mechanisms that prevent tampering and ensure information is authentic.

Six techniques for detecting threats in a complex, dynamic environment:

• Network behaviour analysis — Continuous monitoring with machine learning to spot anomalies and suspicious traffic.
• Data security analysis — Detecting attempts to access or exfiltrate sensitive data.
• Log analysis (SIEM) — Correlating logs and events to identify and respond to incidents quickly.
• Honeypots and honeynets — Decoy systems that attract attackers and reveal their tactics.
• Intelligence-driven security — Security intelligence from diverse sources to anticipate threats.
• Application behaviour analysis — Sandboxing and monitoring to isolate malicious code and exploits.

Strategies for securing IoT devices despite power and resource constraints:

• Security updates — Regular patches, easy to install, without excessive resource use.
• Encrypted communications — TLS / HTTPS to protect data against interception.
• Authentication and authorisation — Keys or digital certificates that limit access to authorised devices and users.
• Limiting network exposure — Correctly configured firewalls and disabling unused services and ports.
• Monitoring and detection — Real-time visibility to catch unusual behaviour early.
• Securing data — Encryption and isolation for safe storage and processing of sensitive data.
