Questions in this quiz (13)
1A known, confirmed attack
Detected when a file or traffic matches a signature pattern:
1- lPS signatures
2- WAF signatures
3- Antivirus signatures
Example: Exploit of known application vulnerabilities- AExploit
- BAnomaly
2Can be zero-day or denial of service attacks (DoS)
Detected by behavioral analysis:
1-Rate-based IPS signatures
2-DoS policies
3-Protocol constraints inspection
Example: Abnormally high rate of traffic (DoS/flood)- AExploit
- BAnomaly
3Flow-based detection and blocking :
- AKnown exploits that match signatures
Network errors and protocol anomalies - BKnown exploits and protocol anomalies
Network errors that match signatures
- AKnown exploits that match signatures
4IPS Components‘ IPS signature databases ‘ Protocol decoders IPS engine (Select 3)
- AIPS signature databases
- BProtocol decoders
- CIPS engine
- DIPS Protocol decoders
- EIPS engine databases
5IPS engine (Select 5)
- AApplication control
- BAnti-virus (flow based)
- CWeb filter (flow based)
- DEmail filter (flow based)
- EData Leak Prevention (DLP) (flow based in one-arm sniffer mode)
- FAnti-virus (flow based in one-arm sniffer mode)
- GIPS (flow based)
- HAnti-spam (flow based)
6Decoders parse protocols.
lPS signatures find parts of a protocol that don’t conform.
For example, too many HTTP headers, or a buffer overflow attempt
Unlike proxy-based scans, IPS often does not require IANA standard ports.
Automatically selects decoder for protocol at each OSI layer- AWhat Are Protocol Decoders?
- BWhat Are Protocol?
- CWhat Are Decoders?
7IPS packages are updated by FortiGuard. (Select 3)
- AIPS signature databases
- BProtocol decoders
- CIPS engine
- DIPS Protocol
- EIPS databases
- FIPS signature
8Choosing the Signature Database
- [blank_start]Regular[blank_end] : Common attacks with fast, certain identification (default action is block)
- [blank_start]Extended[blank_end] : Performance-intensive- ARegular
- BExtended
9In fact, because of its size, the extended database is only available for FortiGate models with a smaller disk or RAM. But, for high-security networks, you might be required to enable the extended signatures database.
- ATrue
- BFalse
10Configuring IPS sensors
- ATwo ways:
Add signatures
Add filters - BThree ways:
Add signatures
Add filters
Add IPS profile in the policy
- ATwo ways:
11IPS Actions (Select 6)
- APass
- BMonitor
- CWarning
- DBlock
- EReset
- FDefault
- GPacket Logging
- HQuarantine
12Which of the following are evaluated first in an lPS sensor?
- AA. IPS filter
- BB. IPS signature
13Which IPS component is updated most frequently?
- AA. Protocol decoders
- BB. IPS signature database
