🔸What Is a Firewall? How Do You Set It Up?
A firewall is a hardware or software network security device that monitors inbound and outbound network traffic. Firewalls, which block the flow of traffic flagged as suspicious or malicious, are considered the first line of defense in the field of network security.

To configure a firewall, you’ll need to:

🔸Secure the firewall. Only authorized administrators should have access.
🔸Designate firewall zones. Evaluate assets of values and group them together according to function and sensitivity. Create a corresponding IP address schema.
🔸Build access control lists. These rules dictate which traffic is permitted to flow in and out of different zones.
🔸Configure related firewall services and logging. Set up your firewall to report to your logging server and disable any services you don’t plan to use.
🔸Test. Use vulnerability assessments to check that the firewall is behaving according to the parameters of your access control lists.

Firewalls analyze network traffic according to pre-configured security rules and only accept inbound connections that follow these rules. Incoming data packets that do not adhere to these rules will be blocked by the firewall, which operates like a guard at the computer’s port—the function is analogous to a bouncer checking IDs at a nightclub entrance. If your firewall is functioning properly, only trusted IP addresses are granted access.

🔹کتابخونه Embetter بهتون اجازه میده که به راحتی از تصاویر یا متن به کمک ترنسفورمر یا مدل‌های زبانی فیچر استخراج کنید و با مدل‌های ساده مثل logistic regression توی scikit-learn پایپ‌لاین بسازید تو چند خط کد!
این کمک میکنه که خیلی سریع عمکرد همه مدل‌های عمیق رو‌ برای تهیه baseline بتونید حساب کنید.

برای نصبش فقط کافیه این خط رو اجرا کنید:

python -m pip install embetter

What Is Shoulder Surfing?

Should surfing is a method of data theft by which a bad actor over the shoulder of a target in order to steal confidential information like passwords and PIN numbers that can later be used to initiate a cyberattack. Like phishing, shoulder surfing is a social engineering technique—meaning it belongs to a class of information security attacks that rely on psychological manipulation to extract confidential information or influence victims to perform actions counter to their best interests.

این نوع حمله یکی از ساده ترین نوع حملات است که در آن مهاجم پشت سر یا پشت شانه های هدفش قرار می گیرد و از بالا یا کنار دست آن در هنگامیکه طعمه مشغول وارد کردن پسورد خودش است یواشکی نگاه می کند و متوجه رمز عبور کاربر می شود.

🔸What Do You Mean by XSS?

Cross-site scripting (XSS) is a type of cyberattack that injects malicious scripts into legitimate websites. XSS attacks use web applications to send these fragments of code—typically as browser-side scripts—to oblivious end users whose browsers execute the malicious script because it appears to originate from a trusted source.
