4. WHAT IS GSM?
The Global System for Mobile Communication
Communication (GSM) is a standard to describe
the protocols for second-generation (2G) digital
cellular networks used by mobile devices such
as mobile phones and tablets.
BENEFITS OF GSM
1. Emergency responses
2. Technological growth
3. Universal data transfer
4. Has international capabilities

5. WHAT IS GSM SECURITY
GSM security is provided for
gsm network subscribers to
communicate securely without
any intrusion. The security here
is covered for the air interface
part and not for the fixed
network part. The air interface is
considered to be weakest for
the hackers. Security for SS7
part was not provided as SS7
was used for few of the
institutions.

6. The GSM security mechanism is covered with following;
*Authentication (used for billing purposes)
*Confidentiality
*Anonymity(used to identify users)
*PIN lock, EIR, personalization, etc.
*Authentication process helps gsm network authenticate the right user. This
authentication procedure in gsm security mechanism is triggered due to
following;
1. On the access to the network
2. Accessing the network for the purpose of making or receiving calls
3. Location update process and the change of subscriber-related information
stored in HLR

7. WHAT IS ACCESS CONTROL?
Access control is a fundamental
fundamental component of data
security that dictates who’s allowed
to access and use company
information and resources.
Through authentication and
authorization, access control
policies make sure users are who
they say they are and that they
have appropriate access to
company data. Access control can
also be applied to limit physical
access to campuses, buildings,
rooms and data centers.

8. TYPES OF ACCESS CONTROL
There are two types of access control. They are;
1. Physical access control
2. Logical access control
1.PHYSICAL ACCESS CONTROL
Physical access control systems are used in homes or
organizations to authorise or deny entry to their premises. It
grants access to employees and contractors who work at or
visit a site by electronically authenticating their PIV
credentials. Physical access control limits access to buildings,
compounds, warehouses, rooms, etc.
2. LOGICAL ACCESS CONTROL
A logical access control system requires the validation
of an individual’s identity through some mechanism such as a
PIN, biometric or other token. It has the capability to assign
different access privileges to different individuals depending
on their roles and responsibilities in an organization.

9. How does access control work?
Access control identifies users by
verifying various login credentials,
which can include usernames and
passwords, PINs, biometric scans and
security tokens. Many access control
systems also include multifactor
authentication (MFA) a method that
requires multiple authentication
methods to verify a user identity.
Once a user is authenticated, access
control then authorizes the appropriate
level of access and allowed actions
associated with that user credentials
and IP address.

10. Why is access control important?
Access control keeps confidential information such as customer data, personally
personally identifiable information, and intellectual property from falling into the
wrong hands. It’s a key component of the modern zero trust security framework,
which uses various mechanisms to continuously verify access to the company
network. Without robust access control policies, organizations risk data leakage
from both internal and external sources.
Access control is particularly important for organizations with hybrid cloud and
and multi-cloud environments, where resources, apps, and data reside both on
premises and in the cloud. Access control can provide these environments with
more robust access security beyond single sign-on (SSO) and prevent
unauthorized access from unmanaged and BYO devices.

12. ACCESS CONTROL SYSTEM

13. CONCLUSION
In the fields of physical security
and information security, access
control is the selective
restriction of access to a place or
other resources, while access
management describes the
process. The act of accessing
may mean consuming, entering,
or using. Permission to access a
resource is called authorization.
