3. SECURITY ISSUES OF E-COMMERCE

4. FIREWALL
• Firewalls are network security systems that prevent unauthorized access to a network.
It can be a hardware or software unit that filters the incoming and outgoing traffic
within a private network, according to a set of rules to spot and prevent cyberattacks.
Firewalls are used in enterprise and personal settings
• A firewall is a computer network security system that restricts internet traffic in, out, or
within a private network. This software or dedicated hardware-software unit functions
by selectively blocking or allowing data packets.
• For example, a firewall rule may say to drop all traffic incoming to port 22, which is
commonly used to log in to computers remotely using SSH (secure shell). In this case,
when a packet arrives with the destination port of 22, the firewall will ignore it and fail
to deliver it to the source IP.

5. E-LOCKING
• An electronic lock (or electric lock) is a locking device which operates by means of electric current.
Electric locks are sometimes stand-alone with an electronic control assembly mounted directly to
the lock.
• An electromagnet attracting a conductor with a force large enough to prevent the door from being
opened. In a more detailed examination, the device makes use of the fact that a current through
one or more loops of wire (known as a solenoid) produces a magnetic field.
• Electronic locks are ideal for use with access control systems. Cutting and issuing physical keys to
individuals is expensive, time-consuming, and inefficient. With electronic access control systems,
'keys' can be a huge of range of things: A code that is entered into a keypad.

6. ENCRYPTION
• Encryption is a way of scrambling data so that only authorized parties can
understand the information. In technical terms, it is the process of converting
human-readable plaintext to incomprehensible text, also known as ciphertext.
• Encryption is a key component in protecting data stored in the cloud, and is used by
cloud backup services to secure and protect user data from unauthorized access.

7. CYBER LAWS
• Cyber law, also known as internet law or digital law, signifies the legal regulations
and frameworks governing digital activities. It covers a large range of issues,
including online communication, e-commerce, digital privacy, and the prevention
and prosecution of cybercrimes.
• If an individual commits an act that violates the rights of a person in cyberspace,
then it is treated as a cyberspace violation and punishable under the provisions of
cyber laws. Since cyberspace is completely different from the physical world,
traditional laws are not applicable here.
