What is Sender Policy Framework (SPF)? Ever wondered how email servers know whether a message is legit or fake?That’s where Sender Policy Framework (SPF) steps in. 🔍 How SPF Helps: ✔️ Verifies legitimate sending servers via DNS records ✔️ Blocks cybercriminals from impersonating trusted domains ✔️ Protects brand reputation and email communication integrity ✔️ Reduces phishing and email spoofing attacks Read more: https://infosec-train.blogspot.com/2026/01/what-is-sender-policy-framework-spf.html #EmailSecurity #SPF #CyberSecurity #PhishingPrevention #EmailAuthentication #InfoSec #DMARC #DKIM #infosectrain

From authentication attempts and directory changes to DNS activity, application errors, and system-level events logs provide the evidence that security controls are working as intended. When monitored correctly, these logs help organizations: Detect suspicious behavior early Investigate incidents with accuracy Meet audit and compliance requirements Strengthen overall security posture Security without visibility is blind. Logs turn infrastructure activity into actionable security intelligence.

DNS Flood Attack vs. DDoS Not all cyberattacks are created equal—understanding the difference between DNS flood attacks and DDoS attacks is crucial for defense: 🔹 DNS Flood Attacks → Overload DNS servers with massive requests (often UDP-based). 🔹 DDoS Attacks → Target ANY part of the infrastructure using botnets to flood with traffic. 💥 Key Differences: ✔ Traffic Type ✔ Goals ✔ Mitigation Strategies 🛡 Defense Tactics: 👉 DNS filtering 👉 Rate limiting 👉 DDoS protection services Read Here: https://infosec-train.blogspot.com/2025/08/dns-flood-attack-vs-ddos.html #DNS #DDoS #CyberSecurity #CyberAttacks #NetworkSecurity #InfoSec #CompTIASecurityPlus #CEH #HackingPrevention #CyberAwareness #ThreatIntelligence #InfosecTrain #ITSecurity #EthicalHacking #DDoSProtection

DNS Flood Attack vs. DDoS Not all DDoS attacks are the same. A DNS flood is a specific type of DDoS that overwhelms DNS servers with massive fake queries. The result? Legitimate users can’t resolve your domain, even if your web servers are perfectly fine. 🔹 DNS Flood Attack → Focused on DNS servers; disrupts domain resolution. 🔹 DDoS Attack → Broader category; floods bandwidth, CPU, or memory with traffic from multiple sources.

DNS Spoofing vs. MITM Attack Cybercriminals don’t break in through doors, they sneak in through your internet connection. 👉 Whatever you do online on a daily basis - visiting a website, buying something online or linking to a Wi-Fi network - each may seem harmless, but this is just one way to open serious risks. What you may not realize is you may be giving away sensitive data to a hacker. 👉 This is the key idea of DNS Spoofing & Man-in-the-Middle (MITM) attacks; they are cyber tricks that redirect your traffic or intercept your communication without your knowledge. 🔗 Read the detailed breakdown here: https://www.infosectrain.com/blog/dns-spoofing-vs-mitm-attack/ ✅ Through awareness of always checking for HTTPS connections, having strong authentication and implementing security measures like encryption and DNSSEC, both individuals and organizations are able to greatly reduce their risk of becoming victim to these attacks. #CyberSecurity #DNSSpoofing #MITM #DataProtection #InfoSec #CyberAwareness #Encryption #OnlineSafety

DNS Flood vs. DDoS – Same chaos, different tactics! Discover how they work & why it matters for your security. 🔹 DNS flood attacks hit DNS servers with too many requests while DDoS attacks interrupt network accessibility by bombarding a target system with traffic. 👉 DNS Flood Attack: For example, consider you are calling the phone book 📞 asking for someone’s number but will a thousand other fake callers are asking at the same time. The phone book (DNS server) gets too busy and won't give you the answer. 🔸 DNS Flood = Blocks the "phone book "of the internet. 👉 DDoS Attack: Consider you have a store and a thousand fake customers rush into your store at the same time. The store (website/server) is too busy for the real customers to get in. 🔹 DDoS = Blocks the actual website or server. 🔗 Read the full article here: https://medium.com/@Infosec-Train/dns-flood-attack-vs-ddos-359b8a221b18 ✅ It is important for organizations to know these differences so that they can better protect and defend their cybersecurity. #CyberSecurity #DDoS #DNSFlood #CyberAttack #InfoSec #NetworkSecurity #ThreatDefense #SecurityAwareness
