It is true that the system development life cycle( SDLC) is the overall process of developing, implementing, and retiring information systems through a multistep process from initiation, analysis, design, implementation, and maintenance to disposal.
Though there are numerous alternative SDLC models and approaches, they all typically include a number of clearly defined steps or phases. Information security must be incorporated into the SDLC for every SDLC model that is used to ensure that the information that the system will transmit, process, and store is properly protected.
Organizations can balance the need for the security of agency data and assets with the cost of security controls and mitigation measures throughout the SDLC by implementing the risk management approach to system development. Critical assets and operations, as well as systemic weaknesses across the company, are identified by risk management methods. Risks are frequently distributed across the entire organization and are not unique to particular system architectures.

what happens if the spoofed source ip address in a syn flooding attack does belong to a machine that is currently running?
The SYN+ACK packets sent by the server may be dropped because forged IP address may not be assigned to any machine. If it does reach an existing machine, a RST packet will be sent out, and the TCB will be dequeued.
What is IP address?IP stands for internet protocol address. It is essentially a numeric value issued to a network device that is used for network device identification and location. IP addresses are assigned to all network devices. IP is an abbreviation for "internet protocol." Your router IP address is the unique identifier for each device connected to your network. For the router to recognize and transfer data packets, a device (such as a computer or smartphone) must have an IP address. The data packets are what give your internet its name. A computer's IP address enables it to send and receive data over the internet. Most IP numbers are solely numerical, however as internet usage expands, certain addresses have letters appended to them.

write the prototype and header for a function called compute. the function should have three parameters: an int, a double, and a long (not necessarily in that order).
The function's name is included in the header, which also provides information about the parameters and the type of data the function will return to the caller function or application. The function prototype and header are given below:
Prototype: void compute(double, int = 8, long = 56565);
Header: void compute(double x, int y, long z)
The name of the function, the function's return type, and a list of the function's parameter types make up a function prototype or declaration. A parameter name may follow a parameter type in the parameter type list, which is a list of parameter types separated by commas. The function evaluation operator is surrounded by the argument list (denoted by a pair of parentheses). Subject to the identifier conventions of C++, the programmer chooses the names of the function and its parameters.
There are two things that a function prototype and a function header have in common. A semi-colon is necessary after the function prototype and the function header needs to know the arguments. The return type on the function prototype and function header is void if a function returns nothing.

channel partitioning based multiple access protocol has chances of more collisions than random access protocols. true or false
False. Channel partitioning-based multiple access protocols typically have fewer chances of collisions than random access protocols.
Multiple access protocols are used in communication systems to regulate how various devices or nodes access the channel or medium that is used to transfer data. Multiple access protocols come in a variety of forms, such as random access protocols and channel partitioning-based protocols.
The channel is divided into distinct channels or frequency bands by channel partitioning-based protocols, and each device or node is assigned to a particular channel or band. As a result, there will be less possibility of collisions between devices using various channels or bands because they won't interact with one another.
On the other hand, random access protocols allow all devices to simultaneously access the channel without assigning any particular bands or channels to any particular devices. As devices attempt to send data at the same time, producing interference and perhaps leading to lost or distorted data, this might cause more collisions.
As a result, multiple access protocols based on channel partitioning often have lower collision rates than random access protocols.
