Introduction:

Embarking on a digital detective mission within the vast landscape of Azure requests data has proven to be an enlightening journey. Armed with queries and a detective’s intuition, we delve into the intricate details of the request table for my Azure project. Join me as we uncover the mysteries behind response codes and gain insights that will enhance our project’s performance.

1. Spotting Overall Response Codes:

requests
| summarize count() by resultCode

Our journey begins with a broad view of response codes. This simple yet powerful query reveals the distribution of response codes, providing a quick snapshot of the overall health of our system.

2. Examining 4XX: Understanding HTTP Error Analysis:

requests
| where resultCode startswith "4"
| summarize count() by resultCode

Next, we focus our magnifying glass on the 4XX errors—the client-side errors. This query allows us to understand the landscape of client-related issues, helping us fine-tune our application and enhance the user experience.

3. Identifying URLs with Excessive 401 Responses:

requests
| where resultCode startswith "401"
| summarize count() by resultCode

The notorious 401 responses can be a headache. By singling out URLs associated with excessive 401 responses, we can pinpoint potential authentication or authorization challenges and ensure a seamless user journey.

4. Identifying URLs with Excessive 5XX Responses:

requests
| where resultCode startswith "5"
| summarize count() by resultCode

Server errors (5XX) can disrupt the user experience. This query identifies URLs generating excessive 5XX responses, empowering us to address server-related issues promptly and ensure a robust and reliable system.

Conclusion:

In the ever-evolving landscape of Azure, our detective work with these queries unveils valuable insights. Armed with this newfound knowledge, we can optimize our Azure project, ensuring a smoother user experience and a more resilient system. The journey into Azure request data may be akin to detective work, but with these queries, we’re equipped to solve the mysteries and elevate our project to new heights. Happy analyzing! 🕵️‍♂️🚀 #AzureAnalytics #DataInvestigation #TechDetective

Here are some common issues that can occur in the development of APIs:

• Inadequate Authentication and Authorization:
  • No proper way to verify users.
  • Weak security measures for authentication like using simple API keys or Basic Authentication without any additional security measures.
  • Not controlling access based on user roles.
  • Exposing sensitive information without restrictions.
    
• Lack of Input Validation:
  • Not checking the type of data received.
  • Allowing attacks like SQL injection or script injection.
  • Not handling unexpected input values like out-of-bounds.
    
• Exposing Sensitive Data:
  • Returning too much information, including passwords, personal data, API Keys, etc.
  • Not encrypting or protecting sensitive information properly.
    
• Poor Error Handling:
  • Revealing internal system details in error messages.
  • Not handling exceptions that can cause application crashes.
    
• Rate Limiting and Throttling:
  • Not controlling the rate at which requests are allowed.
  • Allowing excessive requests that can overload the system.
    
• Not keeping things safe:
  • Not using secure communication protocols or encryption.
  • Failing to protect data at rest or in transit.
    
• Not writing down the rules:
  • Insufficient or outdated documentation for developers.
  • Missing information about API endpoints, parameters, and responses.
    
• Versioning:
  • Making changes that break compatibility with existing clients.
    
• Logging and Monitoring:
  • Not keeping records of requests, errors, or suspicious activity.
  • Failing to set up alerts for monitoring the system.
    
• CORS (Cross-Origin Resource Sharing):
  • Allowing unauthorized access from any origin, potentially leading to attacks.
  • Not specifying which HTTP methods are allowed.|
    
• State and Session Management:
  • Not implementing statelessness properly.
  • Relying solely on client-side sessions without server-side validation.
    
• Secret Management:
  • Storing secret keys or credentials in the source code.
    
• Not Keeping Dependencies Updated:
  • Using outdated libraries or frameworks that have known vulnerabilities.

If you’re a software professional working in the UK mortgage domain, it’s really important to know key concepts to make informed decisions.

Here’s an overview:

• Mortgage Principle: A mortgage in principle is also known as a Decision in Principle (DIP), Agreement in Principle (AIP), or mortgage promise. This is a written estimate from a lender saying that they’ll lend a certain amount to you before you’ve finalized the purchase of your home. It’s not a guarantee but can show sellers you’re serious about buying.
• Interest: The cost of borrowing money. Interest can be ‘fixed’ (the rate remains the same for a set period) or ‘variable’ (can change).
• Deposit: The upfront amount you pay towards the property’s purchase price. It’s typically expressed as a percentage of the property’s value.
  The size of your mortgage deposit will depend on the value of the home you want to buy. For those buying a property to live in, it’s usually at least 5% or 10% of the overall property value. For example, on a property valued at £200,000, a lender may ask for a 10% deposit – which is £20,000.
• Loan-to-Value (LTV): A ratio that compares the size of your loan to the value of the property. If you borrow £80,000 on a £100,000 property, your LTV is 80%. Generally, a lower LTV gives access to better interest rates.
• Mortgage Term: The length of time you have to repay the mortgage. A typical mortgage is repaid over 25, 30, or 35 years.
• Repayment Mortgage: A mortgage where you pay back both the interest and the principal loan amount. By the end of the term, you’ll have paid off the entire loan.
• Interest-Only Mortgage: You only pay the interest on the loan amount each month. At the end of the term, you’ll need to repay the original loan amount in full.
• Stamp Duty Land Tax (SDLT): A tax paid on the purchase of properties in England and Northern Ireland. Scotland and Wales have their own equivalent taxes.
• Mortgage Broker: A professional who offers, negotiates, and/or arranges mortgages on behalf of individuals or businesses.
• Standard Variable Rate (SVR): The default mortgage interest rate your lender will charge after your initial mortgage deal period ends. This can go up or down in response to changes in the Bank of England base rate or internal decisions by the lender.
• Early Repayment Charge (ERC): A fee you might have to pay if you repay your mortgage (or overpay more than the agreed amount) during a fixed or discounted period.
• Equity: The difference between the value of your home and the mortgage you owe. If your home is worth £250,000 and you owe £200,000, you have £50,000 equity.
• Negative Equity: When the value of your home is less than the amount you owe on your mortgage.
• Remortgaging: Switching your current mortgage to a new deal, either with the same or a different lender.
• Buy-to-Let Mortgage: A mortgage specifically for people buying property as an investment, intending to rent it out.
• Affordability Assessment: Before giving you a mortgage, lenders will assess if you can afford the monthly repayments. They’ll look at your income, outgoings, and other financial commitments.
• Conveyancing: The legal process of transferring ownership of a property from the seller to the buyer.
• Mortgage Protection: Insurance policies like life insurance, critical illness cover, or income protection, ensure that your mortgage is paid if you die, fall seriously ill, or lose your job.
• Help to Buy: A government scheme designed to help people buy a home with a smaller deposit.
• Initial interest rate
  This is the initial percentage rate at which we calculate the interest on the mortgage.
• Initial interest rate period
  This is the period during which the fixed or tracker rate applies. For fixed and tracker rate mortgages, when the specified period expires, the rate will revert to the HSBC Standard Variable Rate/Buy-to-let Variable Rate.

Understanding these concepts provides a solid foundation for navigating the UK mortgage domain. If you’re considering obtaining a mortgage, it’s always advisable to seek professional advice or counseling to ensure you understand all the implications and potential costs involved.
