Browse all Security+ study guides →What’s the difference between hashing, encryption, and encoding?
The difference between hashing, encryption, and encoding is what each does to data: hashing creates a one-way digest for comparison, encryption protects data with a key, and encoding changes its format so another system can read it. Choose hashing to check integrity, encryption for confidentiality, and encoding for compatibility.
02What’s the difference between symmetric and asymmetric encryption, and when would I use each?
The difference between symmetric and asymmetric encryption is the keys: symmetric encryption uses the same secret key to encrypt and decrypt, while asymmetric encryption uses a related public and private key pair. Use symmetric encryption for bulk data; use public-key methods for tasks such as secure key establishment, signatures and some encryption workflows.
03How do I remember the differences between IDS, IPS, SIEM, SOAR, and EDR?
To remember the differences between IDS, IPS, SIEM, SOAR, and EDR, attach a job to each: IDS detects suspicious activity, IPS can block it, SIEM connects events from logs, SOAR runs response workflows, and EDR investigates and responds on endpoints. In a scenario, look for the action and the place it happens.
04What’s the difference between authentication, authorization, and accounting?
The difference between authentication, authorization, and accounting is the question each answers: authentication checks who you are, authorization decides what you may do, and accounting records your activity. Remember AAA as identity, permission and record. A successful login doesn’t automatically grant access to every file or action.
05How do common attacks like phishing, smishing, vishing, password spraying, credential stuffing, and brute force differ?
Common attacks differ by how they reach a victim or use credentials: phishing uses deceptive messages, smishing uses texts, and vishing uses voice calls. Password spraying tries a few passwords across many accounts; credential stuffing reuses stolen login pairs; brute-force guessing systematically tries candidates. Identify the delivery channel and the login pattern separately.
06What ports and protocols do I actually need to memorise for Security+?
For Security+, memorise common service ports together with their purpose and transport: SSH 22, DNS 53, DHCP 67/68, HTTP 80, HTTPS 443, SMTP 25, SMB 445, LDAP 389 and RDP 3389 are a useful starting set. Then learn secure alternatives, monitoring and VPN ports. This is a study shortlist, not a guaranteed exam-only list.
07How do firewalls, VPNs, proxies, WAFs, and network segmentation work together?
Firewalls, VPNs, proxies, WAFs, and network segmentation work together by controlling different parts of a connection: firewalls enforce traffic rules, VPNs protect a tunnel, proxies mediate requests, WAFs inspect web requests, and segmentation restricts movement between zones. Use them in layers, with each control matched to the traffic and risk it can handle.
08What’s the difference between vulnerability scanning, penetration testing, threat hunting, and risk assessment?
The difference between vulnerability scanning, penetration testing, threat hunting, and risk assessment is their aim: scanning finds potential weaknesses, penetration testing tries authorised attacks to validate exposure, threat hunting looks for hidden malicious activity, and risk assessment weighs likelihood and business impact. Choose the activity that answers the organisation’s actual question.
09How do I work out ALE, SLE, ARO, RTO, RPO, MTTR, and MTBF questions?
To work out ALE, SLE, ARO, RTO, RPO, MTTR, and MTBF questions, first separate money, recovery targets and observed times. SLE = asset value × exposure factor; ALE = SLE × ARO. RTO is the target recovery time, RPO the acceptable data-loss window, MTTR average repair or recovery time, and MTBF average operating time between failures.
10What should I expect from Security+ performance-based questions, and how should I approach them?
For Security+ performance-based questions, expect to apply security knowledge in a task rather than only choose a letter. Approach each PBQ by reading the goal, checking the constraints, examining the supplied evidence and making the smallest correct changes. Practise explaining your decisions, managing time and checking that every requested part is complete.
Before you choose
What else should I know?
Is this an official CompTIA app?
CompTIA Security+ Practice is an independent study app from Cyber Phoenix LTD. CompTIA and Security+ are trademarks of CompTIA. The app isn’t affiliated with or endorsed by CompTIA.
Does the app explain incorrect answers?
Yes. Practice includes explanations for the correct choice and the alternatives, plus hints when you need help. Concept lessons explain the principle before practice.
Does it include practical exercises?
Yes. The firewall exercise asks you to allow required connections and deny risky paths. It helps you apply network controls; it doesn’t reproduce a live exam question.
Can I download it now?
