RansomeWare Vs SpyWare Vs ScareWare


  • Ransomware:
    •  is a type of malicious software from cryptovirology that threatens to publish the victim's data or perpetually block access to it unless a ransome is paid.
    •  While some simple ransomware may lock the system in a way which is not difficult for a knowledgeable person to reverse, more advanced malware uses a technique called cryptiviral exortion , in which it encrypts the victim's files, making them inaccessible, and demands a ransom payment to decrypt them.
    • In a properly implemented cryptoviral extortion attack, recovering the files without the decryption key is an  intractable  problem – and difficult to trace digital currencies  such as Ukash and BitCoin are used for the ransoms, making tracing and prosecuting the perpetrators difficult.
  • Spyware 
    • is software that aims to gather information about a person or organization without their knowledge, that may send such information to another entity without the consumer's consent, or that asserts control over a device without the consumer's knowledge.
    • "Spyware" is mostly classified into four types: adware, system monitors, tracking cookies, and trojans.
    • Spyware is mostly used for the purposes of tracking and storing Internet users' movements on the Web and serving up pop-up ads to Internet users.
    • Whenever spyware is used for malicious purposes, its presence is typically hidden from the user and can be difficult to detect. Some spyware, such as keyloggers, may be installed by the owner of a shared, corporate, or public computer intentionally in order to monitor users.
  • Scareware 
    • is a form of malware which uses social engineering  to cause shock, anxity or the perception of a threat in order to manipulate users into buying unwanted software. 
    • Scareware is part of a class of malicious software that includes rouge security software, ransomeware and other scam s/w that tricks users into believing their computer is infected with a virus,
    •  then suggests that they download and pay for fake antivirus s/w to remove it. 
    • Usually the virus is fictional and the software is non-functional or malware itself.

Process Vs Thread

The Process and Thread are the essentially correlated. The process is an execution of a program whereas thread is an execution of a program driven by the environment of a process. Another major point which differentiates process and thread is that processes are isolated with each other whereas threads share memory or resources with each other. Key Differences Between Process and Thread : All threads of a program are logically contained within a process. A process is heavy weighted, but a thread is light weighted. A program is an isolated execution unit whereas thread is not isolated and shares memory. A thread cannot have an individual existence; it is attached to a process. On the other hand, a process can exist individually. Each thread has its own stack, so if a thread dies its stack is reclaimed. In contrast, if a process dies, all threads die including the process. Conclusion: Processes are used to achieve execution of programs in concurrent and sequential manner.

Reasoning Vs Inference

Inference: Inference is a general term representing the derivation of new knowledge from existing knowledge and axioms (i.e., rules of derivation) within a single step, and can be one of many kinds, such as, induction, deduction and abduction. For example, "modus tollens" is a rule of inference. Thus, one inference is the derivation of new knowledge using a single step using modus tollens. Inference is about taking in data and trying to draw a conclusion based on the limited information you have in a situation where not all the data is given. Reasoning: Reasoning is in context of a goal (e.g., decide whether a propositional formula is satisfiable or not)  and is carried out via a search process involving multiple inferences. Choices during such search have to be made such as which axiom to "fire" along with which knowledge in order to derive new knowledge. Resolution is a particular kind of reasoning involving the "resolution rule". Reasoning is

Frame vs Packet

Image
Difference Between Frame and Packet     The crucial difference between frame and packet is that frame is the serial collection of bits, and it encapsulates packets whereas packets are the fragmented form of data and it encapsulates segment. Data link layer performs framing process. On the other hand, Network layer performs fragmentation of the data and create smaller chunks known as packets. Another major difference is that a frame includes device’s MAC address while a packet includes device’s IP address. Basis for comparison Frame Packet Basic Frame is the data link layer protocol data unit. Packet is the network layer protocol data unit. Associated OSI layer Data link layer Network layer Includes Source and destination MAC address. Source and destination IP address. Correlation Segment is encapsulated within a packet. Packet is encapsulated within a frame. Conclusion: Frames and Packets function as protocol data units utilized on the
