foundational IT security policies
Acceptable use policy (AUP): The AUP defines the actions that are and are not allowed with respect to the use of organization-owned IT assets. This policy is specific to the User Domain and mitigates risk between an organization and its employees. • Security awareness policy: This policy defines how to ensure that all personnel are aware of the importance of security and behavioral expectations under the organization's security policy. This policy is specific to the User Domain and is relevant when you need to change organizational security awareness behavior. • Asset classification policy: This policy defines an organization's data classification standard. It tells what IT assets are critical to the organization's mission. It usually defines the organization's systems, uses, and data priorities and identifies assets within the seven domains of a typical IT infrastructure. • Asset protection policy: This policy helps organizations define a priority for mission-critical IT systems and data. This policy is aligned with an organization's business impact analysis (BIA) and is used to address risks that could threaten the organization's ability to continue operations after a disaster. • Asset management policy: This policy includes the security operations and management of all IT assets within the seven domains of a typical IT infrastructure. • Vulnerability assessment and management: This policy defines an organization-wide vulnerability window for production operating system and application software. You develop organization-wide vulnerability assessment and management standards, procedures, and guidelines from this policy. • Threat assessment and monitoring: This policy defines an organization-wide threat assessment and monitoring authority. You should also include specific details regarding the LAN-to-WAN Domain and AUP compliance in this policy.

what are the type of web application attacks
Arbitrary/remote code execution: Having gained privileged access or sys admin rights access, the attacker can run commands or execute a command at will on the remote system. Buffer overflow: Attempting to push more data than the buffer can handle, thus creating a condition where further compromise might be possible. Client-side attack: Using malware on a user's workstation or laptop, within an internal network, acting in tandem with a malicious server or application on the Internet (outside the protected network). Cookies and attachments: Using cookies or other attachments (or the information they contain) to compromise security. Cross-site scripting (XSS): Injecting scripts into a web application server to redirect attacks back to the client. This is not an attack on the web application but rather on users of the server to launch attacks on other computers that access it. Directory traversal /command injection: Exploiting a web application server, gaining root file directory access from outside the protected network, and executing commands, including data dumps. Header manipulation: Stealing cookies and browser URL information and manipulating the header with invalid or false commands to create an insecure communication or action. Integer overflow: Creating a mathematical overflow which exceeds the maximum size allowed. This can cause a financial or mathematical application to freeze or create a vulnerability and opening. Lightweight Directory Access Protocol (LDAP) injection: Creating fake or bogus ID and authentication LDAP commands and packets to falsely ID and authenticate to a web application. Local shared objects (LSO): Using Flash cookies (named after the Adobe Flash player), which cannot be deleted through the browser's normal configuration settings. Flash cookies can also be used to reinstate regular cookies that a user has deleted or blocked. • Malicious add-ons: Using software plug-ins or add-ons that run additional malicious software on legitimate programs or applications. • SQL injection: Injecting Structured Query Language (SQL) commands to obtain information and data in the back-end SQL database. • Watering-hole attack: Luring a targeted user to a commonly visited website on which has been planted the malicious code or malware, in hopes that the user will trigger the attack with a unknowing click. • XML injection: Injecting XML tags and data into a database in an attempt to retrieve data. • Zero-day: Exploiting a new vulnerability or software bug for which no specific defenses yet exist.

IP Mobile Communications
Mobile IP provides connection transparency for several entities working together to ensure that mobile devices can move from one network to another without dropping connections: Mobile node (MN): The mobile device that moves from one network to another. The MN has a fixed IP address regardless of the current network. Home agent (HA): A router with additional capabilities over standard routers, the HA keeps track of the MNs it manages. When an MN leaves the local network, the HA forwards packets to the MN's current network. Foreign agent (FA): A router with additional capabilities connected to another network (not the HA network), the FA assigns the MN a local address. When the MN connects to another network that supports Mobile IP, it announces itself to the FA. Care of address (COA): The local address for the MN when it connects to another network, the FA assigns the COA to the MN and sends it to the HA when the MN connects. In many cases, the COA is actually the FA address. The HA forwards any packets for the MN to the COA. The FA receives the packets and forwards them to the MN. Correspondent node (CN): This is the node that wants to communicate with the MN.

Enforce the organization's data classification standard. Vulnerable to eavesdropping: Use encryption and VPN tunneling for secure IP communications. Vulnerable to malicious attacks: Deploy layered LAN-to-WAN security countermeasures. Vulnerable to DoS and DDoS attacks: Apply filters on exterior IP stateful firewalls and IP router WAN interfaces. Vulnerable to corruption of information and data: Encrypt IP data transmissions with VPNs. Back up and store data in offsite data vaults (online or physical data backup) with tested recovery procedures. Inherently insecure TCP/IP applications (HTTP, FTP, TFTP, etc.): Refer to your data classification standard for proper handling of data and use of TCP/IP applications. Never use TCP/IP applications for confidential data without proper encryption. Create a network management VLAN and isolate TFTP and SNMP traffic used for network management.
