knowledge is a dream that can’t come true, but what kind of technical
knowledge is required to become a hacker is the real question. The
intangible skills alone can’t give you success in the field of
information security, you need to have the in depth understanding of
how technology is actually working; you need to understand the
systems and processes, from electrical pulses to radio frequency,
from bits to bytes and from Windows OS to Linux OS. There are many
computer languages are required your attention but to follow the
right direction is the real deal that will lead you to your
things to discuss under the single heading of computer networking,
but as you can’t be an expert on everything so the recommendation is
to know everything a little, at least.
understand the OSI layer model and it protocols (HTTP, FTP, IP, TCP,
BGP, NAT, DHCP etc etc) – protocols depend on the layer of the OSI
model. Learn the art of routing, how router and switches work,
understands the wireless protocols for WiFI hacking (oh come on,
learn something with the intention of learning).
books are available on the aforementioned topics but it is always
recommended to get a mentor who guide you throughout your journey.
You have done or if you are doing any degree in computer science (or
related field) then you are most likely to learn all these topics,
however if you want self study then start your study now because each
topic may cover an entire book.
Operating System Skills
operating system is very crucial to be succeed in infosec world.
Understanding the OS does not mean to install/configure and use the
OS efficiently; it means to understand the concept, the flow and the
architecture of an operating system. You should not limit yourself to
any specific OS, learn as much possible as you can including mobile
OS (Android, iOS etc.).
Programming & Scripting
There is a saying
that, “Programming is not necessarily required to become a
hacker/infosec professional”. Let’s break it and try to understand
this saying, it is true that most of the successful penetration
testers don’t write code but it does not mean that they can’t write
or they don’t understand the coding. So understanding is the KEY, you
should understand the tool you are using for your test and don’t
forget the importance of manual penetration testing and code review.
programming languages for example: C, C++, Java etc. The scripting
languages are also important, including but not limited to: Perl,
Ruby, bash etc.
article,we can conclude that learning is the key and learning is the
most important aspect to survive in the field of information
security, keep in mind that technology is changing everyday and you
need to change your mind at the same speed else you will be kept
behind. Learn the existing, previous and upcoming technology
infrastructure and languages; as you are more likely to break the
code you understand fully.
