physical
security
The physical security domain provides
protection techniquesor security for the entire facility,from the
outside perimeter to the insideoffice space, including all of the
information system resources.because that due to the current
situation so many security attack or cyber attacks we face
them.Physical security can be as simple as a locked door or as
elaborate as multiple layers of barriers, armed security guards and
gate-house placement.physical Security describes security measures
that are designed to deny access to unauthorized personnel from
physically accessing a building, facility, resource, or stored
information; The physical measures & their associated
procedures to safeguard & protect against:
Physical safeguards a person must face before that the logical
safeguards are reached physical security is the first line of
security.example:locked doors,fence,cameras,access badges,locked
computer,security guards,gates and security dogs.
physical object that creates a barrier to unauthorized access.
This includes:
- locks and latches
- safes
- alarms
- guards & guard dogs
- doors & door strikes/frames/closers
- Windows
- ceilings & floors
- walls & fences
just few examples description shown below:
Locked Door

- it is self locking or user must lock
- keeping doors locked is reliant on a policy to due so
- policies must be enforced for locks to work
camera

- cameras is provide security.
- like firewalls,traffic is managed.
- cameras monitor physical traffic of authorized and unauthorized
users.
- can be used in a breach scenario to make sure all users are
authorized.
Locked computers

- locked computers keep unauthorized users from accessing a
computer
- log off or shutdown function used.
- only password allow users onto computer.
- prevent attacker from physical accessing and installing malware
onto computer.
Fences

- Fences can be around entirety of building.
- in breach scenario there can be a "lock-in".
- fences keep all people in or out.
- must be activated by procedure.
Fire Security and
Safety
- Most serious threat to safety of people who work in an
organization is possibility of fire.
- Fires account for more property damage, personal injury, and
death than any other threat.
- Imperative that physical security plans examine and implement
strong measures to detect and respond to fires
Barcodes
First-generation barcodes represent
data as a series of variable-width, vertical lines of ink:
one-dimensional encoding schemeSome more recent barcodes are
rendered as two-dimensional patterns using dots, squares, or other
symbolsCan be read by specialized optical scanners, which translate
a specific type of barcode into its encoded information.
it consist of 3 types:
- Physical security controls-consist of the system and techniques
used to restrict access to a security perimeter,eg:Mantraps,Guard
Dogs
- Technical Controls-it consist of Alarms,Intrusion Detection
systems,CCTV
- Administrative Controls-Restricted Area Authorized Person
only,Access logs,emergency procedures.
Physical Security Attackers : Two Categories
- Outside the company
- From within the company
Preventing Outside attackers
- Natural barriers: landscape and terrain
- Fencing: type and construction
- Walls and ceiling construction: high risk areas
- Gate facilities: security checkpoints
- Frequency of patrols and security check
- Door and window locations and security devices used
- Reception areas: location and control of entry
- Employee surveillance and vigilance
- Parking areas: entrance/exit, access to facilit
Physical Security Preventing attackers from
within
- Ex: Disgruntled or greedy employers or contactors.
- It’s important to implement a physical access control program
in a company and strictly enforce the measures
- If an attacker has physical access to a system they can wreak
havoc.
