Question: If you could improve your network security by implementing only ONE of the following, which would you choose? - Active Directory Hardening - Multi-Factor Authentication (MFA) - Network Segmentation - Firmware Updates My choice: Network Segmentation. What's yours?

رفقا، آینده کسب‌وکار با هوش مصنوعی اصلاً در خطر نیست! هوش مصنوعی ما رو بیکار نمی‌کنه، برعکس کمکمون می‌کنه واقعاً پیشرفت کنیم و متخصص‌تر بشیم 😌 فقط کسایی باید نگران باشن که تخصص و مهارتی ندارن یا کاری انجام می‌دن که AI می‌تونه صفر تا صد انجامش بده. #هوش_مصنوعی #AI

At ISE 2026, Cisco&Microsoft announced expanded collaboration: faster deployments, express installations, and tighter integration for hybrid environments (Azure + Catalyst SD-WAN, Webex/Teams Rooms). MPO-eligible solutions now count toward MACC commitments. Great for cloud-native

CISA ED-26-03 + KEV catalog addition: CVE-2026-20127 & CVE-2022-20775 actively exploited → root takeover risk in SD-WAN fabrics. Actions: inventory devices by Feb 26 EOD, apply Cisco patches, collect AWS logs, hunt for compromise. Federal agencies required.

CVE-2026-20127 (CVSS 10.0) in Cisco Catalyst SD-WAN Controller/Manager: unauthenticated auth bypass exploited in the wild since 2023 → admin access + NETCONF config manipulation. CISA ED-26-03 mandates inventory, patching by Feb 27, 2026, and IOC hunting. Using SD-WAN?check now

Protect long-lived secrets (TLS sessions, VPN tunnels) with hybrid KEMs (X25519 + Kyber). NIST PQC standards are final in 2026—test interoperability and performance overhead now (expect 20-30% latency hit on high-throughput links). Don't wait for full quantum breakout.

SASE convergence is complete: networking + security fully integrated. With rising edge/cross-domain attacks (IoT, 5G/6G), cloud-native ZTNA + SWG + CASB is essential. Attacker breakout time <10 mins—real-time visibility + automated response mandatory. #SASE #NetworkSecurity #Edge

Perimeter is dead—identity is the new boundary. Non-Human Identities (NHI: service accounts, AI agents) carry the highest risk in 2026. Focus on continuous verification, least-privilege for machines, dynamic policies. Implement ZTNA + SPIFFE/SPIRE ASAP. #ZeroTrust #Identity

Gartner warns: Quantum advances will render RSA/ECDSA unsafe by ~2030. Start migrating to PQC (Kyber, Dilithium, Falcon) now—hybrid schemes are the best interim. Harvest-now-decrypt-later attacks are real; build crypto agility into your design. #Cybersecurity #PostQuantumCrypto

AIOps is no longer optional—predictive anomaly detection, automated remediation, and closed-loop ops are standard in 2026. For AI workloads in DCs, sub-1ms latency and 800G+ throughput are baseline. Still on manual configs? Time for serious upgrade. #Networking #AIOps

In 2026, Agentic AI agents (non-human) are exploding and breaking traditional IAM. Need auto-registration, machine credential rotation, and context-aware policy enforcement. Without adaptive IAM for agents, shadow agents become the #1 breach vector. #Cybersecurity #IAM #AgenticAI

در ۲۰۲۶، Agentic AI agents (غیرانسانی) به سرعت در حال گسترش‌اند و IAM سنتی رو نابود می‌کنن. نیاز به identity registration خودکار، credential rotation برای ماشین‌ها، و policy-driven authorization بر اساس context. بدون adaptive IAM، shadow agents ریسک اصلی breach خواهند بود.

The illusion many network admins still have: Firewall is behind NAT, so we’re secure now NAT provides zero real security — it just buys you a little time One of the most critical network security principles: Firewall Hardening. Do you know what steps you need? #CyberSecurity

توهم بسیاری از ادمین های شبکه: فایروال پشت NAT هست پس دیگه امنیت داریم یادمون باشه NAT هیچ امنیتی رو تضمین نمیکنه و فقط زمان می‌خره 👌 یکی از مهم‌ترین اصول امنیت شبکه HARDENING فایروال هست. میدونین چکارهایی باید انجام بدین ؟ #امنیت_سایبری
