Computer Anatomy
Select a part to reveal its role and security connection.Select a component
Hardware, software, identity, and networks work together as one system.
BConverter
Number-System Converter
Change one value and see the equivalent binary, decimal, and hexadecimal forms.Binary
Base 2 uses only 0 and 1. Eight bits commonly form one byte.
Decimal
Base 10 is the everyday system using digits 0 through 9.
Hexadecimal
Base 16 uses 0–9 and A–F. It provides a compact way to display binary values.
CServices
Common Ports & Services
Select a port to see what it commonly supports and what defenders consider.Select a port
An open port means a service is listening. It does not automatically mean the system is vulnerable.

Cybersecurity Vocabulary
Search for a word or browse the cards.ReconnaissanceGathering information about a person, organization, system, or environment before or during an operation.
OSINTOpen-source intelligence: collecting and analyzing information from publicly available sources.
TargetThe person, account, device, application, organization, or outcome an operation focuses on. It may be known first or identified during reconnaissance.
Attack surfaceAll reachable places where a system or person could be exposed to an attack.
VulnerabilityA weakness that may be used to violate a security requirement.
ExploitA method or code that takes advantage of a vulnerability.
ThreatAnything capable of causing harm to an asset.
RiskThe possibility and impact of a threat using a vulnerability.
AuthenticationProving an identity, such as with a password, passkey, token, or biometric.
AuthorizationDeciding what an authenticated identity is allowed to do.
Least privilegeGiving only the access needed for a task or role.
HashA one-way transformation that produces a fixed-style output from input data.
SaltUnique extra data combined with a password before hashing to reduce the value of precomputed lookup tables.
EncryptionTransforming readable data into protected ciphertext using a key.
EncodingChanging data into another representation for storage, transmission, or compatibility; it is not automatically secrecy.
FirewallA control that allows or blocks traffic according to rules.
HardeningReducing attack surface and strengthening a system’s configuration.
PatchAn update that fixes defects or vulnerabilities.
LogA time-stamped record of events generated by systems and applications.
Incident responsePreparing for, detecting, containing, removing, recovering from, and learning from security incidents.
Social engineeringInfluencing people to reveal information, approve access, send money, or take another risky action.
CybersecurityThe practice of protecting systems, networks, applications, devices, and data from unauthorized access, disruption, alteration, or destruction.
NetworkTwo or more connected devices that exchange data and share services or resources.
Zero-dayA newly discovered vulnerability for which defenders may have no vendor patch yet; attackers may try to exploit it before a fix is available.
File systemThe structure and rules an operating system uses to name, organize, store, locate, protect, and recover files on a storage device.
HackingUsing technical knowledge to explore, test, change, or control technology. It is ethical only when it is authorized, scoped, and used responsibly.
EData tools
CyberChef: Transform and Inspect Data
CyberChef applies operations to input and displays the result.1. OperationsSearch for a tool such as “From Base64,” “To Hex,” or “SHA2.”
2. RecipeDrag the operation into the recipe area.
3. InputEnter fake or non-sensitive practice data.
4. OutputObserve, compare, and explain the transformed result.
Decode Base64
Paste Q3liZXJzZWN1cml0eQ==, then use From Base64. The output is Cybersecurity.
Compare Hashes
Use a fake word with SHA2. Change one character and notice how dramatically the output changes.
Add a Fake Salt
Compare robot2026 with robot2026|583967 before hashing. The outputs should be different.
Privacy: Never paste a real password, account token, confidential file, private message, or personal record into a public web tool.
Open CyberChef
FDefensive controls
System Hardening
Select a defense to see why it matters.Patch operating systems, applications, browsers, firmware, and network devices. Remove unsupported software.
Remove unused accounts, avoid shared administrator accounts, use least privilege, and protect sign-in with MFA.
Disable what is unnecessary, limit remote access, restrict firewall rules, and monitor exposed services.
Use unique long passwords or passphrases, password managers, secure reset processes, and modern password hashing.
Enable useful logs, synchronize time, centralize important events, and investigate unusual authentication or system activity.
Keep multiple protected copies and test restoration. A backup that cannot be restored is not a reliable recovery plan.
Protect data at rest and in transit, manage keys carefully, and remember that encryption does not replace access control.
Know the approved configuration, document changes, test one change at a time, and verify the system still performs its intended role.
Competition connection: Cyber-defense events often place vulnerabilities and insecure settings inside virtual machines. Participants inspect the system, fix issues, preserve required services, and watch scoring or evidence of improvement.
