Cyber Security part 2
digital asset:
Cyber security deals with
digital assets, comp, mobile,tablets
A digital asset is a digital entity
owned by an individual or company. Examples include digital photos,
videos, and songs. These assets are not tangible, meaning they
have no physical presence. Instead, they are files that reside on storage
device, such as a local computer or a cloud-based storage network.
Personal data information.
Malware: the program which was installed in the computer is
called Malware.
Bots are bits of code that live on your computer awaiting a
command from the internet to perform acts on your behalf, such as sending a
message to other computers.
Firewall: it watches for certain types of actions, such as
an outsider trying to run something on your computer, and prevents it from
happening.
How do we keep our customers data safe?
The cloud is a location that contains a large number of
computers called servers in a facility called a data center.
Ransomware:
Hackers may could encrypt all the files on your computer so
you can’t use them without password, to get the password you need to pay money
for the password so you can use you computer again. That’s why they call it
‘ransomware.”
Bot:
A bot, short for "robot", is a
type of software application or script that performs automated tasks on
command. Bad bots perform malicious tasks that allow an
attacker to remotely take control over an affected computer. Once
infected, these machines may also be referred to as zombies.
It is nothing but a small bits of code tha sleep somewhere on
your computer, usually in a hidden file. When the right command comes in over
the network they wake up and send messages to other computers using your MAC
address.
What is MAC address?
A MAC (Media Access Control) address is
a unique ID assigned to every internet-connected machine that allows it to be
identified when connected to a specific network. To find the MAC
address on your Windows computer: Click on the Start menu
in the bottom-left corner of your computer.
along
with an IP address (which is networks software), there's also a hardware
address. Typically it is tied to a key connection device in your computer
called the network interface card, or NIC.
The
NIC is essentially a computer circuit card that makes it possible for your
computer to connect to a network.
An NIC turns data into an electrical signal that can be
transmitted over the network.
Every
NIC has a hardware address that's known as a MAC, for Media Access Control.
Where IP addresses are associated with TCP/IP (networking software), MAC
addresses are linked to the hardware of network adapters.
Once
again, that's hardware and software working together, IP addresses and MAC
addresses working together.
As
you've probably noticed, the MAC address itself doesn't look anything like an
IP address
To see the MAC Address:
1. Go to control panelàclick on network and internetànetwork and sharing
2. Click on Wi-fi (internet)àclick on details in the dialogue box
3. There you can see the physical address:
What is firmware?
It is a software for hardware. Firmware is a software program permanently etched into a hardware device such as keyboards, hard drive, BIOS, or video cards. It is programmed to give permanent instructions to communicate with other devices and perform functions like basic input/output tasks. Hardware makers use embedded firmware to control the functions of various hardware devices and systems, much like a computer's operating system (OS) ...
