ASN Lookup Tools, Strategies and Techniques
This article covers the concept of ASN, the different types of ASN, and we were able to test some of the best ASN lookup tools in existence.
Basically, ASN information is another piece of the great networking puzzle that surrounds us, a point in the great Internet ocean that will be overlooked by most of its current users.
Autonomous System Numbers (ASNs) is an IP prefix is a list of IP addresses that can be reached from that ISP's network.
The network operators must have an ASN to control routing within their networks and to exchange routing information with other ISPs.
What is ASN Whois Lookup Tool ?
It searches the entered ASN number in ARIN Whois Database and pulls out the company details who originally registered and is using the specified ASN number.
ASN stands for an autonomous system number, and these numbers represent an entire organization or ISP.
APT Security: What Are Advanced Persistent Threats?
This article covers an overview about APTs. An advanced persistent threat (APT) is among the most dangerous cyber threats a company can face.
These attacks are hard to detect and allow an intruder to hide within a network for months. While hackers stay in the system, a company suffers regular data losses and outages without knowing the cause of problems.
While advanced persistent threats were once considered specifically dangerous to government institutions and large enterprises, the threat landscape is constantly shifting. Now, no organization is safe from these types of attacks.
Because they are difficult to detect, and remain in systems for long periods of time and cause devastating losses to their targets, it's important to educate ourselves.
Knowing what APTs are, how to recognize common signs of their presence in a network, and of course, staying diligent and having a good detection and response plan are essential in protecting any organization from this silent threat.
What is difference between APTs and malware?
Most malware executes a quick damaging attack, but APTs take a different, more strategic and stealthy approach.
The attackers come in through traditional malware like Trojans or phishing, but then they cover their tracks as they secretly move around and plant their attack software throughout the network.
Phases of APT attack:
A successful APT attack can be broken down into three stages:
1. Network infiltration.
2. The expansion of the attacker's presence.
3. The extraction of amassed data—all without being detected.
8 Methods to prevent DNS attacks

Hackers will always try to target your public company services, researching to find weaknesses inside your Domain Name System.
Having a solid DNS hardening policy will help to mitigate most of the attacks described in this guide.
Therefore, Start auditing your DNS zones today in order to secure your DNS servers, collect information, and try to reduce your DNS public information as much as possible.
How to prevent DNS poisoning?
Thankfully, there is an antidote: DNS Security Protocol (DNSSEC).
Methods to protect DNS servers:
1. Use DNS forwarders.
2. Use caching-only DNS servers.
3. Use DNS advertisers.
4. Use DNS resolvers.
5. Protect DNS from cache pollution.
6. Enable DDNS for secure connections only.
7. Disable zone transfers.
8. Use firewalls to control DNS access.
