4.1 Flashcards
Whats video surveillance?
It’s also called CCTV(Closed circuit television) or IP-based cameras can replace physical guards. camera properties are important(focal point, depth of field, illumination requirements)
Whats motion detection?
It’s security monitoring device which can be built-in to the CCTV and can notify us if an activity.
Whats asset tracking tag?
this tag is put on every component owned by the company (routers, cables, fibers, etc) which can help to keep track of them by using a bar-code, a number or even a RFID. This helps with financial records, audits, depreciation by gathering make/model, configuration, location, etc.
Whats tamper detection?
Since we cant watch every equipment all the time, we have the systems monitor themselves(hardware: case sensors, routers, firewalls, alarm sent from BIOS) and we can use foil asset tags for tamper notification as well.
Whats an Identification badge used for?
It’s a prevention method. By using an ID badge we can see the picture, name, and other details which must be worn at all times and sometimes could be a door access or smart card(usually standardized format)
What are bio-metrics used for?
bio-metric authentication is another prevention method which uses fingerprints, iris, and voiceprint. It usually stores a mathematical representation of your bio-metrics. These are more secured since you can change your password but not your fingerprint.
What are smart cards?
Smart cards integrate with devices and may require a PIN for prevention.
What are tokens?
there two different kinds of tokens:
- USB token(certificate is on the USB device.)
- Hardware or software tokens(generates pseudo-random authentication codes)
What are key fobs?
A form of hardware and software method of prevention(software inside the fob creates an authentication code)
Whats an example of software tokens?
The SMS code we receive on our phone for authentication.
Whats the point of having locks?
To prevent unknown people from entering an area, we use locks:
- conventional(lock and key)
- Deadbolt(physical bolt)
- Electronic(keyless)
- token-based(magnetic swipe card)
- Multi-factor(smart card and PIN)
