E-commerce Security, Networking, and Digital Strategy Essentials
E-commerce Security Requirements and Defense Strategies
Core E-commerce Security Requirements
E-commerce security involves multiple requirements to ensure the safe operation of online transactions. These core requirements include:
- Confidentiality: Ensuring only authorized parties can view data.
- Integrity: Guaranteeing data is not altered during transmission.
- Authentication: Verifying the identities of users or systems.
- Non-repudiation: Ensuring neither party can deny a transaction.
- Availability: Services must be accessible when needed.
- Privacy: Protecting personal and sensitive information.
Together, these elements build user trust and ensure secure online commerce.
Availability, Authentication, and Authorization Enforcement
Availability means ensuring that e-commerce systems are accessible and functional when users need them. Authentication is the process of verifying a user’s identity (e.g., via password, OTP, or biometrics). Authorization ensures that authenticated users have permission to access specific resources or perform certain actions.
These can be enforced using various security mechanisms:
- Availability is ensured through redundant servers, backups, and DDoS protection.
- Authentication is implemented using secure login systems, multi-factor authentication (MFA), and biometric verification.
- Authorization is managed by access control policies and role-based permissions (RBAC), ensuring only authorized users can access sensitive areas.
Security Defense Strategies for E-commerce Systems
Securing an E-commerce system involves a multi-layered defense strategy to protect against cyber threats like hacking, phishing, malware, and DDoS attacks. One key defense is implementing SSL encryption to ensure secure communication and multi-factor authentication (MFA) to verify user identity.
Other strategies include:
- Firewall and Intrusion Detection/Prevention Systems (IDS/IPS) to monitor and block suspicious traffic.
- Regular software updates and patching to fix vulnerabilities.
- Role-based access control (RBAC) to restrict unauthorized access.
- Data backups and disaster recovery plans.
- Secure coding practices to prevent attacks like SQL injection and cross-site scripting.
Employee training and customer education also play a critical role in minimizing human errors and social engineering attacks.
Digital Signatures: Requirements and Working Mechanism
A digital signature is an encrypted electronic stamp of authentication that confirms the sender’s identity and ensures message integrity. It is used to verify that a document or transaction has not been altered and that it came from a trusted source.
Requirements for a secure digital signature include:
- Authentication: Verifies the sender’s identity.
- Integrity: Ensures data hasn’t changed.
- Non-repudiation: The sender cannot deny sending the data.
Working Mechanism: The sender’s private key encrypts the hash of the message. The receiver decrypts it using the sender’s public key and compares it with their own hash of the message. If both match, the signature is valid, proving authenticity and integrity.
Encryption and Decryption: Symmetric vs. Asymmetric Keys
Encryption is the process of converting plain text into unreadable cipher text to protect information during transmission or storage. Decryption is the reverse process that transforms cipher text back into readable form, accessible only to authorized users.
- Symmetric Key Encryption: Uses the same key for both encryption and decryption. It is fast but requires secure key sharing. Example: AES (Advanced Encryption Standard).
- Asymmetric Key Encryption: Uses a pair of keys – a public key for encryption and a private key for decryption. It is more secure for communication but slower. Example: RSA encryption.
Both types are widely used in E-commerce, banking, and secure communication.
Differentiating Malware: Virus, Worm, and Trojan Horse
- A virus is a malicious program that attaches itself to other files or software and replicates when the host is executed. It needs user action to spread.
- A worm is self-replicating malware that spreads through networks automatically, without needing to attach to other programs or files.
- A Trojan horse is malware disguised as legitimate software. Once installed, it gives attackers unauthorized access or causes damage.
Technical vs. Non-Technical Malware Attacks
Technical malware attacks are performed using software or code that directly harms systems—examples include viruses, worms, trojans, and ransomware. These attacks exploit software vulnerabilities and often run without user intervention.
Non-technical attacks involve manipulating people rather than systems. These include social engineering, phishing, and baiting, where attackers trick users into revealing sensitive information. They rely on human error rather than system flaws and are harder to detect with just technical defenses.
Networking and Wireless Communication
LTE 4G vs. 3G UMTS: Key Differences
3G UMTS (Universal Mobile Telecommunications System) provides moderate-speed internet access using circuit-switched and packet-switched technologies. It offers average data rates of up to 2 Mbps and supports basic video calling, browsing, and messaging.
LTE 4G (Long Term Evolution) is significantly faster, offering data speeds from 10 Mbps to 100 Mbps and supporting seamless HD video streaming, gaming, and video conferencing. LTE is an all-IP network, meaning it uses only packet-switching for data and voice services.
ADSL, WiMAX, WLAN, and WMAN Differentiation
- ADSL (Asymmetric Digital Subscriber Line) is a wired technology that delivers internet over telephone lines, with different upload and download speeds. It is ideal for home users with limited mobility.
- WLAN (Wireless LAN), such as Wi-Fi, provides short-range wireless connectivity within a building using a router.
- WiMAX (Worldwide Interoperability for Microwave Access) and WMAN (Wireless Metropolitan Area Network) offer broadband wireless access over long distances. WiMAX can cover several kilometers, ideal for rural broadband, while WMAN connects buildings in a city and is used by ISPs and large organizations for urban coverage.
Security Risks in Wireless Networks and Protection Methods
Wireless networks are more vulnerable to attacks like eavesdropping, unauthorized access, man-in-the-middle attacks, and rogue access points, since data travels through open airwaves. These risks can compromise user data, including personal and financial information used in E-commerce.
To protect E-commerce transactions on wireless networks, we use WPA3 encryption, firewalls, VPNs, secure HTTP (HTTPS), and multi-factor authentication. Regular software updates and educating users on safe browsing habits are also important for minimizing threats.
Wireless Communication Definition and Wi-Fi Features
Wireless communication refers to the transfer of data or voice between devices using electromagnetic waves (like radio or infrared) without physical cables. It supports mobile phones, laptops, satellites, and other wireless devices, making it an essential part of modern digital infrastructure.
Wi-Fi, a type of wireless communication, has gained popularity due to:

Extranet, Intranet, and Internet Differentiation
- Internet: A global public network that connects millions of devices worldwide. Anyone can access it using ISPs.
- Intranet: A private network used within an organization for internal communication, accessible only to authorized staff.
- Extranet: An extension of the intranet that allows controlled access to outsiders such as partners or suppliers using secure credentials.
Digital Payments and Financial Systems
ACH (Automated Clearing House)
ACH is an electronic payment system that processes large volumes of financial transactions in batches. It is commonly used for direct deposits, payrolls, and recurring bill payments. ACH networks are cost-effective and suitable for processing transactions between banks securely.
E-Checking: Definition and Working Mechanism
E-Checking (Electronic Checking) is a form of digital payment that mimics traditional paper checks but processes transactions electronically over the internet. It allows users to transfer funds from a bank account to a merchant or service provider online.
The working mechanism involves several steps:
- The user provides routing and account numbers on a secure payment form.
- The system verifies the information and initiates an ACH (Automated Clearing House) transaction.
- Funds are electronically withdrawn from the payer’s bank and deposited into the recipient’s account.
- A receipt is generated.
Bitcoin and Cryptocurrency: Advantages, Disadvantages, and Legality
Bitcoin is a decentralized digital cryptocurrency that allows peer-to-peer transactions without needing a central authority or bank. It uses blockchain technology for secure, transparent, and tamper-proof transaction records.
Advantages of Bitcoin include low transaction fees, borderless payments, and protection against inflation. However, disadvantages include high price volatility, limited acceptance by merchants, risk of cyber theft, and lack of regulation, which may lead to misuse in illegal transactions.
In Nepal, the use of cryptocurrency is currently illegal. The Nepal Rastra Bank (NRB) has banned the use, trading, and mining of cryptocurrencies, citing financial risk and lack of regulation.
Cryptocurrency vs. Virtual Currency
While cryptocurrency is a form of virtual currency, not all virtual currencies are cryptocurrencies. For example, in-game currencies (like coins in PUBG or Free Fire) are virtual but not blockchain-based. Cryptocurrency is decentralized and encrypted, while other virtual currencies may be centralized.
Types of virtual currencies popular in the market:
- Cryptocurrencies (e.g., Bitcoin, Ethereum): Decentralized, blockchain-based currencies.
- In-game currencies (e.g., V-Bucks in Fortnite): Used in gaming platforms.
- Centralized virtual currencies (e.g., WebMoney): Controlled by a specific organization.
