Answer and explanation:
Authentication:
authentication can be done by using the user id and password, by using social sign in or by using the biometrics. Authentication means verify the user who they claim they are and to grant them access.
Authentication works as follows:
Prompting the user to enter the credentials.
Send the credentials to the authentication server.
Match the credentials.
Authorize the user and grants the acces
External Website security:
External Website security is important to protect the website from hackers, electronic thieves and to prevent security breach.
Use of firewall.
Implement the access control.
Use of MVC (Model View Controller) to create different view for different type of user.
Use of encryption.
Use of SSL certificate.
Use of security plugins.
Implement tools and techniques for backup and disaster recovery.
Use of network monitoring team.
Internal Website security:
Use of authentication to identify the user identity.
Use of authorization to provide different user with the specific privileges and access.
Encrypt or hide sensitive web pages.
By implementing IT policies.
Educate the user about the website.
Remote Access Solution:
Remote access provides better security, cost efficiency, ease of management, and increased availability.
Remote access can be deployed by using the RAS gateway (single tenant or multi-tenant):
VPN(Virtual private network), BGP(Border gateway protocol), hyper-V network can be used to provide the remote access.
Remote access can be provided by simple configuration. Remote access involves enabling user, managing their access, protecting the assets, use of remote desktop protocol and managing server sessions, remoteApp and personal and pooled desktop.
Firewall and Basic rules recommendations:
Firewall is important for managing the traffic and providing external website security.
Rules to prevent SQL injection and XSS.
Allow only the specific type of traffic.
Use access rules for IP security.
Implement certain IT policies.
Can implement their own rule.
Wireless Security:
Nowadays Wifi is being used in every organization and it prevents the network from malicious and unauthorized access.
Wireless security can be provided by the use of encryption, decryption, authentication and authorization.
VLAN configuration:
VLAN are important for traffic filtering and providing the logical division of the network.
VLAN can be configured for web interface and can provide web filtering.
In the following manner VLAN can be configured for web interface:
Switching => VLAN => Advanced => VLAN Membership
Switching => VLAN > Advanced => Port PVID Configuration.
VLAN web filtering:
VLAN can be configured between router and firewall, router and gateway, router and switch and by doing so one can filter the web traffic that passes the network.
Laptop Security Configuration:
Use of password, VPN and registering the laptop by their MAC address will provide laptop security. Use of security tool for local machine is also a good option. Use of device level authentication by using local username and password is also a good idea.
Application policy recommendations:
Application policy includes use of cookies, social media integration, access control, generating notifications and implanting other organization and IT rules.
Security and privacy policy recommendations:
It includes the list of security methods to be implemented for traffic filtering, IP spoofing, user authentication and other specific policy for the website.
Intrusion detection or prevention for systems containing customer data:
IPS is implemented behind the firewall and it matches the incoming traffic against the security policies. It matches the signature and handles the intrusion if any and generates the log and alerts for the same.
IDS goal is to identify malicious traffic before it can proceed further into the network. It generates alerts and notification so that the network monitoring team can look after the intrusion.
Use of anomaly based detection and prevention system is the better choice.
