Question

A SOC engineer is handed the following Python snippet that is supposed to read a threat feed CSV file and print only the IP addresses whose 'severity' column equals 'critical', so they can be pushed to a firewall block list:

```python
import csv
with open('feed.csv') as f:
    reader = csv.DictReader(f)
    for row in reader:
        print(row['ip'])
```

The script currently prints every IP in the file regardless of severity. Which single modification will make the script print only the critical IPs?

Accepted Answer

Wrap the print statement in `if row['severity'] == 'critical':`

Answer

Replace `csv.DictReader(f)` with `csv.reader(f)` so the severity column is included

Answer

Change `open('feed.csv')` to `open('feed.csv', 'w')` to reload the filtered data

Answer

Add `reader.sort(key='severity')` before the for loop to group critical rows
