3. Script Hooks • A program that is triggered by an event. • The EasyApache (Apache Update) interface in WHM allows custom hook scripts to be embedded into the Apache configuration process. • WHM -> Home -> Software -> EasyApache (Apache Update).

4. Secure Shell (SSH) • SSH is a network protocol. It is used to remotely log into a machine securely. Keys can be created by cPanel & WHM for the purpose of authenticating the identity of a user during SSH login. Users are allowed to manage SSH keys.

5. Secure Sockets Layer/Transport Layer Security (SSL/TLS) Cryptographic schemes which enable secure transmission between a browser and a web server. SSL/TLS is supposed to protect the sensitive data that is transmitted over the Internet. Such a certificate can be installed on a website by the website owner. This can be done in the “Install an SSL Certificate on a Domain” interface in WHM. This ensures that SSL/TLS protects the website. WHM -> Home -> SSL/TLS -> Install an SSL Certificate on a Domain.

6. Self-Signed Certificate A Self-Signed Certificate is an SSL certificate which doesn’t verify the server’s identity. The reason for it not doing this is, that the entity whose identity is certified by it, had signed it. Users are usually warned by the browsers regarding self-signed certificates’ authenticity. A self-signed SSL certificate can be created in the “Generate an SSL Certificate and Signing Requests” interface in WHM. WHM -> Home -> SSL/TLS -> Generate an SSL Certificate and Signing Request.

7. Sender Policy Framework (SPF) SPF is a feature that is meant to allow the verification by a recipient server that the domain that is specified in the From: field has actually sent the message. SPF should be enabled to prevent one’s server from replying to spam that forged one’s domain name as part of the address of the sender. SPF functions only in the event that SPF is being used by both, the sending as well as the receiving mail servers.

8. Server Name Indication (SNI) SNI lets clients request a specific hostname at the start of the handshake process. In this documentation, SNI refers to this protocol with regard to Apache. In the context of servers, let us touch upon the topic of servers of web hosting companies. These servers that are leased by web hosts, store the files of websites. Web hosting companies also provide the services and the technologies that are needed to make a website accessible over the Internet. These web hosting service providers are known as the “Best Website Hosting Company” or as the “Best Windows Hosting Company” or as the “Top Cloud Hosting Company” when these provide the most efficient hosting service.

9. Server Profile Those server roles that collectively allow one to optimize a server in order for a specific function or task to be performed. A server profile can be selected in the “Server Profile” interface in WHM. WHM -> Home -> Server Configuration -> Server Profile.

10. Server Roles Server roles refer to a certain collection of services. These are meant to ensure specific server functionality. In the context of servers, the servers of web hosting companies come to mind. These servers store the files of a website and make these files available over the Internet, through the technologies that are provided by web hosting companies. The web hosting companies that provide reliable web hosting service are often referred to as the “Best Website Hosting Company” or as the “Best Windows Hosting Company” or as the “Top Cloud Hosting Company”.

12. Service Manager It is a software by which the services and the processes on a machine are monitored. It can be enabled as well as disabled in the “Service Manager” interface in WHM. WHM -> Home -> Service Configuration -> Service Manager.

13. Service Proxying Local services are configured, by service proxying, to proxy requests for the domain of a cPanel account to a remote server.

14. Session (Login Session) Login session refers to the period of activity that is in between the time when one logs into and then logs out of a service or an account. A new security token which is valid only during that particular session is generated by each cPanel & WHM session.

15. Shell Fork Bomb Shell Fork Bomb is a malicious process. A cascade of new processes are created by it for the purpose of using the system resources of a server. This crashes the server. The “Shell Fork Bomb Protection” interface in WHM provides protection against shell fork bombs. WHM -> Home -> Security Center -> Shell Fork Bomb Protection.

16. Simple Mail Transfer Protocol (SMTP) SMTP is the standard protocol by which email messages get transmitted across the internet. SMTP is used to send mail to the Mail Transfer Agent (MTA) of a mail server.

17. Skeleton Directory Skeleton Directory is a directory which defines those files as well as subdirectories that are owned by new accounts by default. When an account is created, a copy of the skeleton directory is contained in the new user’s account. These directories can be created in the Skeleton Directory interface in WHM. WHM -> Home -> Account Functions -> Skeleton Directory.

18. Smart Host Smart Host is a type of email relay server. An SMTP server is permitted by it to send emails to an intermediate mail server, prior to sending messages to their ultimate destination.

19. Source Guardian SourceGuardian refers to PHP loaders which utilize a binary byte code and often encryption that entails multiple levels. A PHP loader can be selected in the “Tweak Settings” interface in WHM. WHM -> Home -> Server Configuration -> Tweak Settings.

20. Spam and Spam Box Spam refers to unsolicited emails, which are sent in bulk by an automated system. Apache SpamAssassin and BoxTrapper are certain features that are included in cPanel & WHM. These help to reduce the amount of spam that one receives.

21. Spam Box Spam box is the directory in which spam messages are stored by Apache SpamAssassin, when the Spam Box feature is enabled. These messages are stored by the system in the spam folder of the email account.

22. Spam Score Spam score refers to a certain value that is assigned by Apache SpamAssassin to every email message. It is based on the number of traits that are spam-related within a particular message. When a message’s spam score is high, it is more likely to be spam.

23. Spoof A spoof is a type of a cyber-attack. In it an attacker appears as some other user. This is accomplished by concealing one’s identity through data’s falsification. SPF should be enabled in order to make it challenging for spammers to carry out spoofing.

24. Subaccount Subaccounts can be created by cPanel account users. These use the same information with regard to login and password when it comes to FTP, Web Disk services and email. Password synchronization is maintained by the system in between each of the allowed services of the subaccount. Subaccounts can be managed by a user in the “User Manager” interface in cPanel. cPanel -> Home -> Preferences -> User Manager.
