You can follow my currenct projects on GitHub. This is where I post all from Java to C# and all other relevant code that I want to share with the world.

Some of my favorite moments

Strategies &

Cyber threats!

 

 

 

Ethical hacking, has become more

popular over the world, and as well

I'm living my dreams out upon security

threats!. To prevent against the

recently updated security vulnerabillities

exposed by OWASP, exploit-db,

packetstormsecurity, 1337day etc.

 

I'm preparing an investment, upon

my own motivation, to get several certifications, which I will attend to

eventually. At this moment, I'm studying within InfoSec books.

 

I finished my graduation at Copenhagen Business School North, and now studies on KEA - Københavns Erhvervsakademi

which is also pronounced The Business Academy. Started at the education the 20-08-12.

It takes 2½ year as a Computer Scienst, to complete the graduation.

 

Currently I'm avaliable to new job opportunities within InfoSec.

As shown below, some methods to implement in a company to secure against security threats, or even on personal usage.

 

  • OpenTC strategies
  • Cryptographics
  • Shell & Physical security
  • Social Engineering tecniques
  • RFID insecurites
  • IPS/IDS, Firewall restrictions
  • IT-security politics

 

As shown, a different methods of preventing against exploits build upon vulnerabilities, are to be broken down in concepts.

 

OpenTC, stands for Open Trusted Computering, which is a great way for securing against attacks, but is not the only solution to be done.

ModSecurity is also some set of security which can be implemented, but should be restricted.

 

Iptables is commonly used as a Linux firewall, and can allow a lot of security impelementations, to make sure you will keep malicious users out.

You do not want to make the job easier for the attacker than given.

User accounts should be restriced, and should think out-of-the-box, to ensure quality, permissions has to be set as with precaution!.

 

Cryptographics, should be used when deliver an internal/external message to a client, within gpg, comming by default in Linux, this should be used to send messages, and also replace the files, to confuse the attacker, if the OS were to be compromised.

 

As Max commonly saying, to people who are not aware of security, and how it should be handeled -

You should treat shell access, as it were physical access.

 

Social Engineering tecniques, should also be taken seriously!.

This is a great threat to a company, if were (e.g. Attacker got into the IT comapny building, droping off a infected USB, carrying a rootkit on it, that has a payload to execute when opened upon a computer).

You got to make the personnel aware of several SE attacks.

 

RFID Insecurities, is something, which not many companies has taken seriously. But hey comon, if an attacker were desperate, he could deploy an attenna from Yagi-Uda 2,412GhZ, and start deauthenticating victims, becomming the man in the middle! - while you might not knowing, the next step were to sniff your password!, or to do some other privilige escalations.

 

IPS/IDS, Firewall restrictions, as mentioned firewall for Linux, such as Iptables, you could do a lot of things with this!. But it's a great start. IPS/IDS, are usually good, but in some advantages, it's giving false alarms. This might be usfull for some sys admins though, to check the log. But at the end of the day, if that's get's the job done, then everyone is happy right?. Snort, Kismet is to be mentioned, when doing some security researcing on the network.

 

IT-security politics, is bascially the main reason on securing a company / private use. Let's face it. there is nothing such as 100% security nowadays. Security is divided up in layers. The main factor here is, there will always be vulnerabilities, since there will always be humans involved. Companies need to focus on what is satisfying them, upon security messurements.
